3D model description


This is a medallion that you can wear around your neck. Of course it can also be opened, so you can put something in it. Now you can always carry something precious with you :-). The images show, that the front is actually a sliding lid. Sliding the lid up opens the medallion.
The internal space is 32.5mm wide and 5mm high. The pendant.stl on which it can be hung on a chain, is also a closing mechanism. When the medallion is hanging, the pendant keeps the lid closed. Therefor, this medallion cannot just open unnoticed, if you wear it around your neck.

I printed this medallion in PLA. Then I put it 6 times in the primer. Then I applied the red and silver paint. Under the silver is also blue paint. Finally I taped the lid and added black.

The pendant is attached to the back by means of a piece of paper clip. If it is around 1mm thick, it is good to use.

I also included a total assembly STL so you can see the whole object in 3D. The filename is “complete.stl”.

If you have any questions feel free to ask :-)

3D printing settings

This medallion is designed for an FDM printer, with a nozzle opening of 0.4mm. The print resolution I used is 0.1mm. The back.stl and lid.stl parts must be printed with print support material.

Hi! I started my own website now. All new models I make will be posted there first from now on. I may post some in the future, but only when I have time. To see all my new work, go to: Yes it's in dutch, but you can set it to the language you want. It's on the top right corner of every page :-). With the exception of payment models. If I have new ones, I will still offer them here :-)
