I love the Joy-cons.
Having said that, I think they don't get the respect they deserve, always being the one controller being passed around on game nights, or always in fear of being replaced with a more "fitting" controller.
I've set myself a simple goal, design a grip for the joy-cons that would allow people to recognize how awesome they really are... and I think I'm pretty close.
So, without further ado, I present to you, the GRIP (cause we all love an all caps NAME, do we not?).
so most awesome Joy-con grip ever made!... to this point in time.
After many attempts, with downloaded parts and with my own creations, and many iterations and fine tuning the GRIP grips the Joy-cons effortlessly (some sanding might be required) and is griped most comfortably for long gaming sessions (I, now, prefer it over my pro controller, which was bought as research for this project).
Love your Joy-cons!
The best ones I've got done were in an UP Mini 2.
With the following settings:
Layer height: 2mm
Recommended support at 30' (Depends on the quality of your printer. the part that locks the Joy-con in place must have some support for it to work.)
But you can play with it, more infill = more weight (I like mine light) etc.
Print standing up so the grips touch the bed.
