Canister Keychain 3D print model

Inside it have some little space - you can open it by left lid and store there what do you want.

Also you can use wire to connect keychain to the ring.

I printed file for visibility... it has no lid and no post-processing, so you can make much better.

It is strongly recommended to use SLA printer. Also you need to take into accout sizes of parts to assemble them => scale them depended on your resin and printer. I used 95% scale (from 100%) for details which needed to be inside the others bigger details - it is side grips. Ans you can use 105-110% for upper lid.
