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:

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

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:

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.

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.
