I've made this cable holder to secure the Ender 3 S1 Pro extruder flat cable. When this cable is fully extended, it starts pulling the plugs on the motor that makes the extruder horizontal movement, and also on the limiter switch plug.

Can be printed in PLA or other filaments, I've printed it in PLA and it's strong enough.

Is to be printed sideways without supports or adhesion (brim), please use 100% infill density.

This part is to be screwed using the original bottom screw/nut, there is a slot for the nut, so you don't need to use a wrench, just an allan key. Use a 3 mm screw to close the clip, a PC tower normaly come with some extra 3mm CDRom screws.
