Joycon Cartridge Grip

thingiverse

I've had great success printing the Joycon grip, which securely holds four game cartridges in place. To achieve the best results, I recommend printing this part vertically. The tight tolerances of the grip rails require some extra attention. It's essential to sand down the outer faces of each rail incrementally and thoroughly clean out the inner rails until the joycons slide in effortlessly.
