openGrid Gadget - Generic Holder/Clip Generator

2026-01-27 Update: Added clip_stem_length parameter, to offset the clip from the board. Can be used to hold items of specific shapes.

2025-11-22 Update: Now the threads have blunt start by default, which should help prevent cross-threading and overtightening. Models with blunt threads have a decorative 'lock' symbol at the bottom. If you prefer the earlier version, or want to use this model with David's original snaps, you can change 'threads_type' in the customizer.

Recommended to use with self-expanding snaps.

An open-source generic holder/clip generator for openGrid. The shape, size, thickness, and orientation of the holder are fully customizable. 

When it comes to mounting custom objects to openGrid, BlackjackDuck's Multiconnect Part Generator is a good solution. But in some cases, I find a flexible "clip" easier to use than a regular under-the-object holder, as it allows me to take the object from the front rather than from above. So I designed these with a front tip for easier insertion, and an optional knurling pattern to increase friction and prevent slipping.

If you don't need a clip, simply disable the tip/knurling and use it as a regular holder. The customizer supports both vertical and horizontal orientations, with additional adjustments like a tilted entry point. Overall this model is versatile, filament-efficient, and reasonably strong when used with self-expanding snaps.

I usually print these with PETG. Depending on how flexible you want the holder to be,  you can also print with PLA or TPU.

Feel free to use the code, and any suggestions or contributions are welcome. GitHub repository
