The stopper has a M4 counterhole. Simply mount it on top of the cheap 2020 belt tensioner. Now the carriage can't leave the rail anymore.

On the other end of the rail sits the x axis endstop to do the same.

The model was designed around the great mods from Kevinakasam (belted Ender 3, Frank 2.0 fan duct, the Y axis linear rail mod and the KlackEnder). Thanks for that!

Model printed with a 0.4mm nozzle and 0.2mm layer height in ABS.

If you like my designs, you can buy me a coffee on Ko-fi!
