Gridfinity! 4mm Pittsburg Screw Driver Holder/Organizer: Updated

Update: 1/22/2025

I have recently gotten into organizing with Gridfinity so I thought I would modify to fit a 3x4 Gridfinity. Holder is slightly narrower and longer to accomodate the 3x4 grid.

Pittsburg Tools (Harbor Freight) sells a cheap micro bit screw driver. The tool is nice but the case is junk. I made a new holder/organizer for my tool box. Holds all the 4mm bits that come in the set, all labeled.

There an angled hole in the top right so you can set it down while working.

I added a file with _No_Text. This one still has the large text for PHILLIPS, FLATHEAD, HEX and TORX, but I needed a smaller nozzle to print the small lettering next to the holes.

Check your file after slicing. The holes for the bits don't go all the way down so if you don't print with enough infill they are unsupported and they will fail on the inside of the part.
