This very quick to print and easy to install thing adds slots to your PrintrBot for Tweezers, Screwdriver, and Hex Wrench. Tools that we can't be without, but are constantly searching for. Never again! Note: I'm adding ToolBelt B for stability. Prevents the tools from clanking. Pretty much locks you into Screwdriver at the rear though. Parts are available separately, or as a one shot PrintBot ToolBelt AB build. Open Scad Source code included. Those are the files ending in SCAD. Take it apart and learn something. OpenScad is easy and simple to learn. OpenScad.ORG This thing is dedicate to Padawan, without who none of this would be possible.
