Made for the precision screwdriver kit using the shell of the PINECIL & TS100/101 ALL-IN-ONE CASE as a starting spot to get started. The case is the same size, just made custom inserts to fit my screwdriver kit, top insert also doubles as a screws and parts tray for while your working! The full recommended hardware list is as follows 6 M3x25mm Hex Socket Head Cap Screws, 6 M3 Nuts and 12 M3 washers, 3mm drill bit to clean out the holes, and blue locktight to keep the screws from loosening themselves! best made of PETG, but should also work fine in PLA. also 30mm M3 screws can work in a pinch they are a bit too long, but that's all I had on hand at the time of taking pictures
