Kwickset Follower

thingiverse

This follower fits 12.5mm Kwickset lock cores with an actuator tail cutout. It's designed for printing on flexible filaments like TPU, which expands when stuffed over the core end, securing tightly in the lock and holding driver pins down while pushing out the core. Print quality matters to ensure smoothness that won't catch springs or master wafers. The design isn't perfect but worked better than available followers. I used it to re-key my Kwickset locks with success.
