Toroidal-End Zipper Pull Handle

A basic parametric zipper pull handle with toroidal end(s). OpenSCAD file included for customizations.

The toroidal ends are closed-loop, such as those found on TravelPro luggage (or at least the model luggage that we have). On such luggage, the metal slider is crimped to hold the pull handle in place. Alternatively, a zip tie or small keyring etc could be used to attach this pull handle.

For highest strength, print with many perimeter layers and 100% infill.

[UPDATED 2/6/23: Added a new version that OpenSCAD renders better, for slicing without errors. Also enabled "grip" surface in this version.]
