Here's my story in bullet points:
- I bought a "My 'lil Sew and Sew".
- I put it on my stool precariously...
- It fell...
- Tried to turn it on and it didn't move the sewing arms and such.
- Opened to find out the plastic holder for the motor was broken; so no grip for the teeth the motor spun.
- Made this in F360.
Nothing else really. Print at 100% infill in your desired material.
For now it was a little on the tight side I think. Still works, but may need to be modified with say a 105% print.
