M3 Hex Bolt Thumbscrews

thingiverse

I had some M3 bolts with hex heads just collecting dust that I wanted to repurpose as bolts for my printer's bed. To make levelling easier, I created these thumbscrew addons from scratch. The design features a "sacrificial bridge" that lets you print without supports if you use a 0.1mm layer height - you should be able to punch through the thin layer with ease. A STEP file is included so you can modify it for other screws if needed. Edit: I uploaded v5 of the design which includes a longer "neck" perfect for use with my East 3D Gecko.
