Parametric Snap Pins

These new snap pins rectify the shortcomings of my old pin library. They offer easier insertion, increased tolerance to varying printer calibrations, and better adhesion to the build platform. Incorporate this library into your OpenSCAD designs or utilize customizer for exporting pins and holes suitable for other programs. Recently, I introduced thin fins in the holes that create slits upon differencing. These deceive slicers into producing webs enhancing the strength of conical hole ends. This feature considerably improves vertical hole strength and can be disabled in other situations if necessary. For creating either free or fixed holes, allowing rotation or not, I recommend using white lithium grease to lubricate the pins. It aids in easier insertion and removal while ensuring smooth rotation without squeaking. However, note that only the ends of snaps are designed for tight fitting since they're flexible, accommodating varying printer tolerances. The rigid parts of the pins are significantly smaller than the holes, assuring ease of insertion.
