Hex Screw Clamp with Gear output

thingiverse

I've been observing these motors on sciplus for quite some time now, and just recently discovered them on Amazon. Since their rising popularity indicates that others might be utilizing them, here's a model that makes mine significantly more effective. A picture of the motor I designed this for is included. Instead of using the outer edges of the threads as a shaft or investing almost $1,000 in a tap set for 7/16 ACME threads, clamp these to either side of the screw shaft and drive something with a 40mm hex. Six M4 nuts and six 30mm M4 screws are required. The new version includes provision for an optional M3 setscrew, which will necessitate two M3 nuts and two M3 setscrews. A gear is situated on the shaft to facilitate driving a rotary encoder, along with an additional gear for the encoder. For those who are curious, I utilize this setup to drive gears like the large one included in this assembly.
