There's some measurements missing so I took some liberties like placement of the threaded holes and the stop for the shaft. Here's what I gotHey Guys, sorry for the slow response, I wasn't getting notifications on this thread for some reason.
Here is what I am looking at. Most of these dimensions can be modified to make life easier on your side if needed.
The only two things I can change are the inside shaft diameter (has to fit the shaft of the motor I have) and the shaft length can be not shorter than specified (again to maintain clearance give the motor in hand).
Looking forward to your thoughts.
PM me your email address and I can send you the .stl so you can print it out...
