Nintendo Switch Replacement Latch for Joy-Con Controllers.

thingiverse

This is a replacement part for the lock on the Joycon controllers. Designed to be easy to print on FDM printers, requiring minimal supports and post-processing. I've been printing at 0.05 layer height, but it should also work with lower resolution settings. The part is compact, with a small footprint that demands a well-prepared print surface. It should detach successfully without a brim; I've printed nine units in my testing, with only one incident of detachment. I recommend printing slowly to minimize the risk of detachment. A brim can also be used if needed, but try printing without it first. The part is already correctly oriented for printing: the hole and pin face upwards, while the smaller rectangular surface rests on the print bed.
