NEMA 23 Protective Shaft End Cover

prusaprinters

<p>After getting jammed in the kidneys with the protruding shaft on my CNC machine's NEMA23 stepper motors, I cut down some half liter water bottles to cover the end of the motors. They worked somewhat, but got knocked of easily and I finally decided I should do something more permanent. Hence this design. I made four to use on all 4 motors on my machine. The two in the the front (the Y axis motors) were the ones I would bump into, but there is also the issue of bending or having something getting wrapped up in the protruding shafts.</p> <p>These press fit on pretty tightly, but are still easy enough to remove.</p> <p>Great accuracy is not required. I used PETg and .3mmm layers.</p> <p>I don't know if all NEMA23s are the same dimensions.</p> <p>The green motors shown are on my Probotix Comet. The Meteor, Asteroid and Nebula use the same steppers, as well and other machines.</p> Category: Machine Tools
