Cap nut feet for 1/4-20 wing bolt legs on the Vernier Dynamics Track (black aluminum extrusion)
thingiverse
I went through the OpenSCAD file and verified/changed anything that needed changing -- to be honest I'm not sure I changed a thing other than changing the size back and forth once. I think it was set up for 1/4-20 cap nuts with little to no tweaking. The file provided is the one I printed on a Prusa Mini Plus. The Vernier Dynamics Track system, ca. 2007, has adjustable feet that consist of a wing bolt and a threaded rod 'leg' that is capped originally with a soft rubber foot. The feet disappear or fail over time, leaving the hard bolt end to scratch the lab tables. This cap threads onto the bolt with little effort but fits securely and snugly. I have printed in PLA so far, but plan to try it in TPE for a little additional grip.
