Apple Pencil Pro ergonomic grip sleeve TPU
A slide-on TPU sleeve that thickens an Apple Pencil Pro or 2nd generation (8.9 mm across with one flat side, 166 mm long) to a 13 mm grip for long drawing sessions, easing hand fatigue without covering the double-tap zone or the magnetic flat. The bore is 9 mm with a matching flat so the sleeve does not rotate, the outer has three soft finger flats, and it is 60 mm long with 2 mm minimum wall. Print it upright in TPU at 95A, or in PETG with a 0.2 mm larger bore.

Design a 60 mm long TPU grip sleeve with a 9 mm bore that has a 7.5 mm wide flat on one side to match an Apple Pencil Pro, an outer diameter of 13 mm with three shallow finger flats, 2 mm minimum wall, 1 mm chamfers at both ends and a 0.1 mm bore clearance.

Generic pencil grips are round and let the flat side of the Pencil spin out of place. In SpeakCAD you say which Pencil you own and how thick a grip you want, preview the sleeve in the browser, refine the finger flats in the chat, then download the STL.

Yes. SpeakCAD slices the part on its servers with OrcaSlicer and your printer's official profile (380+ printers, including Bambu Lab, Prusa, Creality and Elegoo), and you download the G-code (a sliced .gcode.3mf for Bambu Lab printers). 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.
