And the Oscar goes to...OPENSCAD !

Configurable Oscar statue for self-printing on 3D printer

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.

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:

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:

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 !


Lotus blossom from the 3D printer

This beautiful lotus blossom was 3D-printed with very favorable PLA filament in interesting green camouflage shade:

To avoid support I used the Cura option - Make Overhang Printable -

This makes it easy to print the object without support, brim / raft, etc. on my anycubic delta Kossel plus 3D printer. The result can be found as a make on thingiverse.com:

Samsung Galaxy Note 4 smartphone cases for flexible filament

For my smartphone Galaxy Note 4 i've already tried many cases to print and use. Pretty much everything that's offered on thingiverse at designs, I've tried. So far, unfortunately, there was none created/designed especially for flexible filament like TPU or similar.
That's why I created this design with the Fusion360 software. Since I am not yet a Fusion360 professional, it was also a very good training to familiarize myself with this very complex CAD tool.

After several hours I had created the first case and already printed. Looks very good and it fits very well, the flexible filament is ideal for such purposes as it is very good and easy to process (almost like PLA), but on the other hand has really just the flexbility needed for such purposes.

Below are some pictures of the design printed with TPU in different shades:

I have now published the design on thingiverse, it can be found under the following link:

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

In order to change the backside with logos, font, icons, smilies or similar, I created another design with fusion360, which has a cutout in the back. This section can then be provided with a separate inset separately created with fusion360, which then contains the respective logo or icon.

Here are some pictures of how it might look like when printed:

 

The grid structure is not implemented in the design but comes out by settings of the CURA Slicer (Zero Top- / Bottomlayer). In the infill pattern I've selected the setting QuarterCubic, resulting in a nice optical grid effect on the finished printed object:

This design is also published on thingiverse and can be found here:

The flexible TPU filament from sainsmart was easy to print with my delta 3D printer anycubic Kossel Linear Plus. The printing speed was set to low speed (20mm / s) to avoid filament jamming at the extruder.

Phoneholder for car vents

For a long time was looking for a suitable and easy to print smartphone holder for the car. The design should be as flexible as possible adaptable to different smartphone dimensions, be stable and easily removable. For the latter requirement, I finally arrived at the attachment to the ventilation slot, in which case, in particular, the stable design and solid print of the attachment is important.

At #Thingiverse I found what i was looking for. The selected design consists of a total of 4 parts, is very easy to put together and meets all my needs. In addition, it also looks nice, or can be customized by color of the filament to the individual needs or the color environment in the car. Another advantage is that all parts are only plugged together and thus quite simply everything can be disassembled again, or, for example, the attachment to the venting slot can be printed several times and the rest can then be simply relocated as needed in the car. In my BMW 225xe there are ventilation openings in the dashboard on both the driver's side and the passenger side, and there are also suitable openings in the middle. I will therefore print the attachment directly in the appropriate amount and then attach to the openings, so then depending on the needs Samrtphone holder can be attached to the various places in the car.

A picture is worth a thousand words, so below is my printed object as I mounted it on the driver's side:

This is how it looks when my smartphone is plugged into the holder:

Overall, everything is very stable during the ride, nothing wobbles or makes noises, even during fast cornering, there are no problems. Below is the link to my make on thingiverse:
