DEFINITELY STILL NEEDS SOME TWEAKING
It doesn't fit snug (pretty loose) but it definitely works. Honestly just wanted a "free" single joycon controller grip, and all the ones online were weird. Holds the controller decently well and I don't mind using it for snipper clips. If you print it a little smaller you might be able to get a tight fit but shrink at own risk. Don't want to damage the controllers trying to fit it in tight.
Printed a prototype in glow in the dark filament for some fun :D
Let me know if there are anythings that could make this better <3
Printed it settled on its back and there are a lot of supports that need to be removed and sanded down. However that was the most stable way I could find to print it.
took about 3 hours and 40g of PLA
