Thumb Head for Cap Screws
thingiverse
Snaps onto the head of a cap screw to make it easier to turn by hand. Instructions Very much a work in progress, I haven't test printed yet. This part is basically a library for you to customize to fit your needs (please comment if it works for you, and let me know what values you use). Print (it's upside down) Press onto cap screw using dual pliers, a vise, or press (see http://downloads.makerbot.com/support/pdf/Thing-O-Matic/Docs/Stepstruder%20MK7%20Assembly.pdf pages 4-5 for ideas) Warning: If F5 mode in OpenSCAD shows something wrong, try F6 mode. It might just be the dev version I'm using, not sure.
