Apple Pencil Pro desk tray with USB-C adapter pocket
A desk tray that stores an Apple Pencil Pro or 2nd generation (166 mm long, 8.9 mm across) in a half-round groove, with a second groove for the shorter Apple Pencil USB-C (155 mm), a row of 5 mm pockets for spare tips and a 22 x 13 mm pocket for the small USB-C to Pencil adapter that always goes missing. The grooves are 9.5 mm wide with the flat side up so the Pencil does not roll, the tray is 180 x 60 x 15 mm, and it prints flat with 2 mm walls.
Pen trays sold for desks are too wide for a Pencil and let it roll off. In SpeakCAD you describe which Pencils you own and how many tips you keep, preview the tray free in the browser, add a slot for an AirTag or Pencil cap in the chat, then download the STL.
Design a 180 x 60 x 15 mm desk tray with two 9.5 mm wide half-round grooves 170 mm and 160 mm long for Apple Pencils, four 5 mm diameter tip pockets 6 mm deep, a 22 x 13 x 9 mm pocket for the USB-C Pencil adapter, 2 mm walls and 1 mm fillets.
