Where can I find normal cheap off-the-shelf parts for a robot arm?

Question

Robotics

I wanted to find and did not find cheap parts for the manipulator for the robot layout. That is, so that there are parts that, if connected with servos, such a standard claw could turn out, or maybe there are some drawings for a 3D printer?

Answer 1

For example, here www.thingiverse.com/thing:34829 - see the thing files tab
I would model from scratch for the existing servos, but this is only if you want to get confused :)))
