I´ve made an Nintendo Switch Joy-Con Strap Holder for both sides.
Supports are included just print out and go on Outline slower because of Ghosting from Logos.
Print both sides.
The Gap between Support is 0.15 mm and Model should be with a little Force easy to break off with Pliers.
Also there is a Hole for a Screw with Diameter 4 mm.
Have Fun and leave a Like.
I have made this because i play Fitness Boxing Switch and always had to put Strap off.
But I wanted a Solution so here it is, i have Two pair Joy-Con.
