Yazzo Tube Attach for Pololu Universal Motor Mount

thingiverse

I have need to attach a bar or or tube, securely to the shaft of a motor. I purchased these universal motor mounts from Pololu: http://www.pololu.com/catalog/product/1203 That part gives you a nice solid aluminum chunk with 4 machine screw holes on it. Then I just had to figure out how to utilize that part to connect my carbon fiber tubes. This thing brings the universal mount together with the tube at a 90 degree angle to the shaft. Very good when you're trying to use the motor as the muscle behind a swinging arm. Although this this is very similar to this other thing:http://www.thingiverse.com/thing:6164 It is not strictly a derivative, as it's design is completely different and the only thing they share is the ability to connect a tube to a motor shaft. Instructions 1) Print one of these out, assuming you've purchased the Pololu motor mount thing. 2) Put the set screw into the motor mount, but don't tighten it all the way. 3) Slip the universal mount into this thing 4) Align the universal mount such that the set screw faces the opening in the outside of the tube 5) Put 4 #4-40 screws into the universal mount from the outside of this thing. Basically tighten the universal mount to the body of this thing. 6) Slip the whole assembly over the motor shaft, and tighten the set screw until it is secure. 7) Slip your tubing or rod into the other opening 8) Rejoice! The OpenScad is provided, and you can change anything from the thickness of the universal mount you have, to the hole spacing, size of tubes, etc.
