Kindle Paperwhite one-hand page-turn grip ring
A stick-on ring grip for the back of a Kindle Paperwhite (176.7 x 127.6 mm on the 2024 model) that slips over two fingers so the tablet hangs from your hand and your thumb reaches the page-turn edge without gripping. The ring has a 22 mm inside diameter and a 4 mm profile, sits on a 40 x 40 mm base plate 2 mm thick with rounded corners, and is placed off-centre in the prompt to suit right or left handed reading. Print it in TPU for comfort or PETG for a firm feel, base down.

Fit notes
Commercial ring grips are round and too small for a Kindle, and downloaded ones assume a phone. In SpeakCAD you describe your e-reader, whether it wears a cover, and your hand, preview the grip in the browser, refine the ring size in the chat, then download the STL.

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.
