Quick Release Lever for 4mm bolt
thingiverse
This rapid-release lever design, suited for my filament drive (http://www.thingiverse.com/thing:7173), might find utility elsewhere. Assemble by printing parts with support material; alternatively, an STL contains both components. Only the lever needs support. Post-print, remove excess material, insert the pin through the lever, and attach the bolt to its designated location via the pin.
