This is a custom joycon comfort grip for the Nintendo Switch. The main idea of this design is that the joycon rails have been tilted outward by 20 degrees to make the overall controller layout more similar to a standard controller. It's been separated out into 3 pieces to make printing/finishing easier, and also to make it more customizable with different pieces.
Eventually, I want this to grow into a wide variety of pieces that can be easily interchangeable, so people will be able to make the perfect joycon grip to fit their own personal comfort, and style preferences. I encourage everyone to remix this with their own pieces, or comment with suggestions or ideas you would like to see with this.
IMPORTANT NOTE: This thing is untested. I hold no responsibility for damage to consoles or peripherals from using this/these items. If it doesn't fit right, don't try to force it. [that being said, it's just 3d printed plastic, just go slow and carefully and it should be fine]
print all pieces standing upright, with the bottom up, for strength, and to keep the rails and grip smooth.
I test printed this with 3 shells, 1 mm floor/roof thickness, and 5% infill. It's plenty strong, but the grip feels a bit light and flimsy. I'd suggest using more infill and thickness for the grip, to make it feel a bit more robust.
Sand the parts smooth, and paint if you want to. It's not necessary, but this can give it a more polished look. If you paint the rail section, be sure to mask of the sides where the Joycons slide in and out, to prevent paint rub off and added thickness. I'd also recommend using spray on rubber on the grip to give it a better texture to hold on to.
This is designed to be held together with two m3 0.5 nuts, and two m3 0.5 13-16 mm long. However, it can also bee glued together or printed as one piece with just a little tweaking to the files.
Insert two M3 0.5 nuts into the slots on the crest piece, and line them up with the holes on the back.
Fit the crest and the grip into the slot on the rail section.
Insert two M3 0.5 screws into the holes on the back, and screw them into place.
