One‑piece printed super mini robotic palm-movable

Boost MeIf you like this design, thank you for your support!  Update 2026.9.1 I have also uploaded the AMS multi‑color printing version of the mini manipulator. You may visit the link below if you are interested.   AMS multi‑color printing version: https://makerworld.com/zh/models/3238578-single-piece-print-mini-mechanical-hand-ams#profileId-3669062   Description This is an ultra‑mini robotic hand with 21 movable joints, enabling a wide range of flexible hand gestures. No assembly is required. It features an integrally‑printed design for immediate use right after printing. It only generates minimal easy‑to‑remove supports and can be printed with just 13 g of material.   The design has been verified through multiple sampling trials. The movable joints feature moderate damping. After completing the first‑time printing and removing the supports, simply flex the movable joints, and they will move smoothly. Notes This axial joint is relatively tight and requires firm twisting. Do not worry about breaking it, as the rotating shaft is designed with sufficient strength. Keep twisting until you hear a click, then the joint will become movable.   There is actually a certain range of lateral movement angle at the base of each finger. If you cannot bend it easily by hand, use a tool to pry the gap side‑to‑side until it becomes loose.   After fixing the above two spots, the joints of the other fingers can be twisted with relative ease.   Or you can also watch my full‑length operation video for the operating procedures:   In fact, there is also a large‑size model close to the real‑life 1:1 scale. So the current model is just its cute mini version, only one‑quarter the size of the original, yet it retains all fully movable joint parts!

I would greatly appreciate it if you could give me a free boost, as it will motivate me to create more! Boost MeIf you like this design, thank you for your support!
