thingiverse

To work with the belts from McMaster Carr, redesign pulleys based on your .2" pitch belt dimensions. Although Erik's script is helpful, adjustments might be needed as it seems to overcompensate for pitch reduction. Ensure to note that the script works in millimeters and remember to uncomment the teardrop section. After downloading OpenSCAD, print test pieces and make required adjustments. The script doesn't account for a captive nut gap but the plastic can securely hold a set screw of the right size.
