robotic hand

WARNING

This model is highly complex and still in development. I’ve made it public early due to community requests; however, it is not yet polished, and there is a high likelihood that issues will occur.

This project is intended for users who enjoy tinkering, modifying, and troubleshooting rather than those looking for a fully refined, plug-and-play experience. 

I will be updating the model and instructions as I receive feedback and implement improvements.

Stl files

If a component does not have a note specify a quantity, you only need to print one.

The only parts that require multiple prints are:

• Screws
• Rubber band holders
• Pulleys

Printing

Due to how similar some parts look, it is strongly recommended to keep parts separated while printing and organizing.
Mixing parts between different fingers may cause assembly issues.

All components should be printed using a 0.2 mm nozzle and PETG filament.
