I made these to reposition my bed motor on my tronxy p802e. My old motor was wearing out and I wanted to make room for a better more powerful motor. Also, I wanted a better belt clamp that would make sure the belts were fairly level.
The motor mount screws down to the board that my printer is strapped down to. Thus, I really could have removed the brace you see in the bottom of the motor images. I moved the motor to the right a few mm and a little lower under the bed. Lowering the motor made more room for the insulation under my bed as it was rubbing just slightly before.
