HAHAHA!
Thats my theory with the blender, wife says no - So now I just dump the failed prints into acetone and make glue.

I think my ABS rods are too weak. I printed them with the layers going along the length which was better for less friction (mind you, perfect movement with these and printed LM8UU).

Going to print some again going vertically which might strengthen them, then work on the printed bearings.

The printed nuts/bolts was more a way off idea - would not try this with motors.

But want to try it out with as many printed components.
