This is a remix of Olvin's case for the Pinecil soldering iron. I used his CAD files and also the Pinecil 3D model available here:

Besides adapting it for the Pinecil I made other small changes:

1. Use of magnets for closing
2. I removed the holes for the screws
3. I changed the location of the hole for the hex tool

I used some 3mm x 1.75mm magnets I already had. Please download the Pinecil holder from the original design. I am also sharing the STEP files in case someone needs to modify the case.
