Nintendo Switch Joy-Con comfort grip for single controller
A palm-filling grip that a single Joy-Con slides onto for sideways two-player sessions in Mario Kart or Smash. The Joy-Con body is 102 x 35.9 x 28.4 mm with a dovetail rail on its inner face, so the grip carries a matching 10 mm rail with 0.2 mm clearance and a small lock lip at the top that clicks against the release button. Two rounded handles extend 60 mm below the controller with a 32 mm diameter to mimic the Pro Controller, and a cutout leaves the SL and SR shoulder buttons and the strap rail fully exposed. Print it rail-up with 2.4 mm walls so the dovetail comes out crisp.

Yes.

G-code sliced for your printer costs the same as the STL: included in every plan, free for a part you shaped by hand, 4 credits without a plan for a part with AI work in it. Pick your printer on the printers page to see its profile.
No. SpeakCAD runs in the browser on your phone or computer: the chat, the 3D engine and the live viewer load in the tab. The only file you download is the finished STL, 3MF or sliced G-code.
