This is a Einsy case for the Prusa Bear MK3/S. It's a remix of Juan Puchol's great work. https://www.thingiverse.com/thing:3901001 with some inspiration from a remix shown on the Bear FB group. (I'd give credit for that but I can't find the post; sorry). I made the main case all one piece and did various mods. Also there is a version of the cover for each Bear frame color. There are other parts you may want/need that you can get from Juan's upload on Thingiverse. This post is only the parts I modded.
UPDATE: Added new version of the case to be able to mount a Raspberry Pi Zero 2 W on the back of the Einsy board. Also a frame you'll need to attach the Pi to the Einsy - use mine not the one from Prusa - mine is based on theirs just better. Link to Pi mounting instructions.

You will need supports for the bear logos on the case and cover. It's a bit tricky and results may very. I used PETG.
