Claw
thingiverse
Some useless telescopic claw as it is. Made of mop and old bycicle brakes handle. I still don't figured out what it can be useful for, exept making scary sounds. The major part is an experimental screw-nut bearing and shafts. Can't find a proper spring for the return movement. UPD: somehow spring isn't necessary. Cord is enough rigid so it pushing the muff back with enough force. https://youtu.be/w_gUUKqIyew https://youtu.be/fiDVP8Sj9aA
