This is a basic grip I created for the Nintendo Switch Joy-Cons.

The girps should print fine at either .1mm or .2mm layer height and the joy-cons slide in easily. The light wholes are functional but are fairly dim.

These finish pretty nicely with some sandpaper and painting. I've had a lot of fun customizing them.

No supports required just make sure to print it standing up straight.

There are no locks but friction is a good helper
