Note
You can re-use 2 belt lengths from the Ender 3, but you still need one more ~350mm length.
Tip
You can re-use 3 limit switches from the Ender 3, if you want to cut them off the PCB's but you'll still be missing 1, so you need to order AT LEAST 1 more, it is probably easier just to buy a new set if you go with this option. The recommendation is to go with the endstop mod.
