Summary

I bought a couple geared steppers from Trinity Labs which ended up being the shorter shafts.

Like a normal hacker I took a design I liked and worked it into fitting what I have on hand.
Sketchup did a surprising job with this :P

V1 has the same exact holes as the original Tinkey Struder just with a wider back to line up the shaft a bit better. (I hope, currently testing)

V2 has a longer base to fit mounts for greg extruders.

I really needed the V2 only but figured I'd release them both.

Instructions

Print V1 or V2 depending on the mounting you need. (May slightly be off???)

Print the Idler from the original Tinkey Struder.

Use longer motor mounting bolts :(

***More info as I make progress

Update 1:

  • It looks like making the dimensions for an exact fit was a mistake, filing down the original idler is probably required :(
  • It might be neccessary to file or edit the body down by about half a millimeter, my shaft is long enough so I can adjust the hobbed gear some but i dont know if i trust it yet
