Spice jar for grenade-sharp things

Since more and more bags and packaging of various spices occured on our spice rack , I was looking for some beautiful and practical spice jars.

Requirements

3D- printable should be the most important feature of the object, so my first stop in Internet research was  thingiverse.com once again. There I noticed an admittedly unusual design of a spice jar in the form of a hand grenade.

Design

For hot spicy things such as cayenne pepper and chilli this design seemed very suitable:

 

img grenade spice jar Design is available on thingiverse for Download

Details

The advantage of the design is that it can be printed in a very uncomplicated way. There are 6 different parts to print:

 

img greande PartsThe red rimmed parts (metal ring and magnets) must be added separately. However, I have initially dispensed the magnets, to open and close the container on the lever works but not so elegant as it might with magnets.

3D-Print

Printing of the items was very uncomplicated. Support structures and largely Raft could be omitted. The material used was cheap PLA filament of owlsat (ebay) for only 16 € per kg.

All was printed on my anycubic i3 mega with a 210 degree nozzle temperature and a tape-backed printbed area. Thus, it was possible to print without heating of the printbed.

First, the lower shell was printed in green PLA:

 

img grenade case

Here it is important that you print bottom-up with the underside upwards. The object is positioned that way as default in the slicer. Otherwise it would have to be printed with support. I printed with 0.4mm nozzle and 0.25mm resolution, at rel. high printing speed of 80mm / s. Only the first layers were printed at reduced speed at 40mm / s.

Since all other parts should be printed differently in color, a filament change was required. Afterwards the printing countinued  with the lever in PLA silver gray:

As shown, the lever could also be printed without support also with 0.4mm nozzle and 0.25mm resolution at 80mm / s print speed.

Same color the two small parts needed to be printed for mounting at the bigger parts. Therefore, these were sliced and printed in a common print job. Due to the small size here, they must be printed with a small Raft, for better printbed- adhesion.

img kleinteile grenadeLast but not least, the lid and threaded attachment for the housing had to be printed. Both should be done in dark brown, so both objects were printed together in one print job.

img deckel greande

The thread attachment is best printed in the correct position, ie positioned top upside . Then you can print without support, because the overhangs shouldn't be a problem.

Assembly

The assembly of the parts is very simple according to the exploded view shown on image in the head of this post. Prior to assembly, no further machining of the parts, such as grinding, sanding etc., should be required, the tolerances of the parts have been considered sufficiently large in the design. The threaded cover can be screwed into the housing easily and fits well. The (ornamental) lid on the threaded cover must be secured with a suitable adhesive.img grenade open

After assembly, the cover for filling the inside can be easily removed and screwed on again at any time. The spout opening can be easily opened and closed again without magnets via the lever.

And the Oscar goes to...OPENSCAD !

Configurable Oscar statue for self-printing on 3D printer

img oscar openSCAD 02

Design idea

At the annual Oscar ceremony, these decorative Oscar trophies are presented. I wanted to create a statue based on this design, which should be configurable and of course also 3D-printable.
I wanted to give this object as a gift to a good friend, as a thank you that he has produced our wedding film so wonderful.

Realisation

The original template of the Oscar statue is available in the Internet in various image formats. Starting from a good photo, I  began to be creative with excellent help of Opensource 3D software Blender.

 

img oscarBlender01

Blender is freely available as software and can be downloaded for free at blender.org. This gives you a lot of possibilities to get creative in 3D. However, the software is not "self-explanatory". Therefore, as a blender beginner it is recommended to get acquainted with the immense variety of functions of this tool. There are a lot of good tutorials and tutorials on the net here, youtube is a hot tip here, as there are some very good video tutorials on Blender available. But I did not only need the design as a blender model, but it also needed the Labeling of the socket should be configurable, yet another very useful CAD tool had to be included. The open-source tool OPENSCAD can be used to create geometric bodies using a programming language. The bodies can be parameterized at runtime via appropriate OPENSCAD customizers via appropriate program parameters or variables. OpenSCAD is also available as a free download via openscad.org.

In any case, I recommend that you download the latest version as a development snapshot, as the stable versions currently do not have the customizer functionality. Tutorials are again very abundant in the network. Especially recommended for beginners are the tutorials available on the OpenSCAD homepage.

Last but not least  the Blender model had to find its way into the OpenSCAD environment. By default, Blender does not offer the option to export models in OpenSCAD format. However, a corresponding add-on is available via github. After the download and successful installation of the add-on in Blender you have the option in the export menu of Blender to select the format openscad. Thus the generated file can be opened in OpenSCAD. In OpenSCAD, the model structure is available as a polyhedron body. The net- structure of the model is stored via corresponding coordinates in the form of a multimatrix. In order to provide the socket with configurable writings, the program code generated from Blender has been correspondingly supplemented in OpenSCAD and provided with parameters for the OpenSCAD customizer:

img oscarstatue openscad 01

As a parameter, besides the text line, I have made available  also other parameters such as font and font size. This allows the socket to be largely labeled or configured as desired. In OpenSCAD, the program code can also be adapted by the user at will to his own interests, so there is still room for further changes and improvements.

Once the parameters have been set via the customizer, an STL file can be generated from OpenSCAD for 3D printing. However, due to the complexity of the multimatrix of the Oscar model, the rendering takes a little longer, depending on the performance of the computer being used. On my DELL G3 laptop with Core i7 8.Gen. CPU and GTX1060 graphics card as well as 32GB RAM  it's relatively fast, after about 10 seconds the rendering is finished.

Since OpenSCAD is also the basis for the customizer provided by thingiverse ONLINE, the model available on thingiverse can also be configured directly online on thingiverse.com. However, I only use OpenSCAD locally on the PC for the corresponding OpenSCAD models, because the thingiverse customizer online in my browser is unfortunately not reasonably usable.

3D-Print

The 3D printing of the STL file generated from OpenSCAD was then prepared using the slicer software CURA. In Cura I have set the layer thickness to 0.2mm, 10% Infill is absolutely sufficient. I added a PAUSE-AT-HEIGHT extension to change the color of the filament after printing the base. I also had to print support because the overhangs on the model's arms were too big:

img cura oscarstatue 01

Overall, the print on my anycubic i3 mega 3D printer took just under 4 hours.

The result is published as make on thingiverse.com

3D printing: KitchenAid adapter for soda stream

3D-Print: KitchenAid Adapter for Sodastream

Our KitchenAid Sodastream looks very chic, so beautiful in black / silver:

img kitchenAid Soda

After some Problems at the beginning it works very well now. Bubbles our excellent Bühlertäler tap water. However, it has a small flaw: there is no suitable glass bottle for this model.

Neither Sodastream nor the Kitchenaid manufacturer provide suitable products for this purpose. That's a pity, so it was obvious to see if there is a suitable adapter with which smaller standard glass bottles with standard threaded fasteners can be docked to the kitchenaid connection.

First I tried the following part:available on thingiverse:

img sodastream v2 threadedpart
That was also very straightforward and easy to print. After testing i found out, only for sodastream with screw thread suitable, so not for our KitchenAid sodastream.

Next thing i tried was this:
img sodastream536857
Also not suitable for our kitchenaid, because the lower edge was missing for the gripping arm.

Unfortunately so, nothing suitable for our device was available on thingiverse.com as stockpart. That's why I took the appropriate measurements, first from the Kitchenaid / Sodastream bottleneck:

img Flaschenhals kitchenAid

then from the bottleneck of a smaller lemonade glass bottle:

img Flaschenhals Limonadenflasche

With these measurements, I was able to use the CAD software fusion360 to construct a suitable adapter that makes the glass bottle fit the Kitchenaid connection. The result is prepared for 3D printing as an STL file available here on thingiverse.com for download .

As printing material i recommend a material as stable as possible such as ABS or similar to give the adapter the necessary strength and stability. Support material or brims / rafts for print-to-bed adhesion are not required for printing. The print resolution should not be set too low due to the modeled thread, I have made good experiences with 0.15mm at 0.3mm nozzle size.

IMPORTANT !!
Please be careful when using the adapter. The Sodastream is a pressure device, and applying rapid pressure to a device not meant for such things can cause explosions and severe injury !!
I may not be held responsible for any damage or injury that may occur when using the adapter. Use at your own risk !

三星Galaxy Note 4智能手机套适用于柔性灯丝

对于我的智能手机Galaxy Note 4,我已经尝试了很多打印和使用的案例。 几乎所有在设计上提供的东西,我都尝试过。 到目前为止,遗憾的是,没有创建/设计特别适用于TPU或类似的柔性灯丝。这就是我使用Fusion360软件创建此设计的原因。 由于我还不是Fusion360专业人员,因此熟悉这种非常复杂的CAD工具也是一项非常好的培训。几个小时后我创建了第一个案例并已经打印出来。 看起来非常好并且非常适合,柔性灯丝非常适合这样的用途,因为它非常好且易于加工(几乎像PLA),但另一方面实际上只有这种用途所需的灵活性。下面是一些 用不同色调的TPU印刷的设计图片:

 

我现在已经在thingiverse上发布了设计,可以在以下链接中找到:

https://www.thingiverse.com/thing:3474919

为了用徽标,字体,图标,表情符号或类似物改变背面,我用fusion360创建了另一个设计,后面有一个切口。 然后可以为此部分提供单独的插页,该插页使用fusion360单独创建,然后包含相应的徽标或图标。

以下是一些打印时的外观图片:

 

网格结构没有在设计中实现,而是通过CURA Slicer(Zero Top- / Bottomlayer)的设置实现。在填充图案Quartercubic中,对完成的印刷对象产生良好的光学网格效果:

这个设计也发布在thingiverse上,可以在这里找到:https://www.thingiverse.com/thing:3475001

sainsmart的柔性TPU灯丝易于使用我的delta 3D打印机anycubic Kossel Linear Plus进行打印。 将印刷速度设定为低速(20mm / s)以避免挤出机中的长丝堵塞。

img cura settings Note4 Flexcase

由于表壳的底边是圆形的,因此建议在Cura-Slicer的“实验”部分设置选项'Make Overhangs Printable'。 这稍微改变了Cura的几何形状,以便可以在没有支撑的情况下打印该区域中的悬垂:

通过这种调整,打印背面边缘应该没有问题:

汽车通风口的手机座

长期以来一直在为汽车寻找合适且易于打印的智能手机支架。 设计应尽可能灵活,适应不同的智能手机尺寸,稳定且易于拆卸。 对于后一种要求,我终于到达了通风槽的附件,在这种情况下,特别是附件的稳定设计和实心印刷是重要的。

在#Thingiverse,我找到了我想要的东西。 所选设计共包含4个部分,非常易于组合并满足我的所有需求。 此外,它看起来也不错,或者可以根据灯丝的颜色来定制,以满足个性化需求或汽车的色彩环境。 另一个优点是所有部件仅插在一起,因此非常简单地可以再次拆卸所有部件,或者,例如,可以多次打印到通风槽的附件,然后可以根据需要在汽车中简单地重新定位其余部件。 在我的BMW 225xe中,驾驶员侧和乘客侧的仪表板上都有通风口,中间还有合适的开口。 因此,我将以适当的数量直接打印附件,然后将其连接到开口,因此根据需要,Samrtphone支架可以连接到汽车的各个位置。

这就是我的智能手机插入支架时的外观:

总的来说,在骑行过程中一切都非常稳定,没有任何摆动或发出噪音,即使在快速转弯时也没有问题。 以下是我在thingiverse上制作的链接:

可定制的线轴抽屉,用于回收空灯丝线轴

与此同时,我的anycubic变热,几乎永久使用。然后以适当的量消耗所需的长丝。这就引出了一个问题,如何处理空灯丝线轴,扔掉会太糟糕了!当然必须有一个好的和有意义的应用程序。做了一些研究后,我找到了解决方案。在多种情况下,可以使用开源软件opencad之一进行设计,以便在适合于相应线圈尺寸的线圈中进行打印,然后可以将其用作小型零件盒或类似物。我将其修改为混音:https://www.thingiverse.com/thing:3198728因此,现在可以使用空灯丝。此外,它们可以堆叠在一起,作为节省空间的小零件杂志。宜家桌腿由金属制成,因为线圈可以与它堆叠在一起。以下照片显示了我的解决方案:
