Ender 3 S1 Pro Y-Axis Stepper Mount

thingiverse

A replacement y-axis stepper mount for the Ender 3 S1 Pro. Tested on my machine which has a gulf coast robotics y-axis rail kit but this is as close as a 1:1 copy of the stock mount as I could get in terms of critical dimensions. It uses the stock mounting bolts and stock limit switch. I have beefed up the mount significantly so it should be more durable, I will update this if it fails down the road. This is a tight fit by design, if your corners are not on point you may need to go in with a small chisel or utility knife to clean them up on the mating surface to the rail. I reduced the need for support as much as possible but you will need supports for some features. I printed my draft versions with regular PETG and that seemed strong enough. I printed the final product using a carbon fiber filled PETG filament for a little extra toughness. I suspect this is overkill.
