Get best of the week

Hey.

Assembled a toy, sharing with you.




Hand drive from the fingers of your hand. Each finger bends at 2 joints, but requires only 1 traction due to leverage. But there is a minus: a decent effort is required, for example, I couldn’t wrinkle a beer can at least halfway no matter how I tried.

Each “tendon” thrust is made of 2 mm steel wire, drilled at the tip, and fastened in a finger with a wire from a paper clip. Screws 2.5mm 16mm (and shortened when assembling the fingers) I bought in Leroy.

3D models are here.

Initially, I wanted to make my fingers more “human”, and print the whole finger at a time (I printed HIPS), but in the end it didn’t work out, my details stuck together. I cut each finger to print separately, but the assembly turned out to be difficult. There were other options, including with syringes, or rather, I started with them. There were also metal. With soft tendons and elastic bands to return to a straightened position. Not all 3D models remained, deleted as unnecessary.

The thumb brought the most problems: if you make it better to fold into a fist - the grip decreases, you increase the grip - the fist is not collected. What happened is a compromise. Further, in my opinion, only add another joint.











Has nothing to do with dentures!
