The simplest and most effective cable holder.

I was tired of the main cable flopping about and all the solutions I've seen have been too elaborate. This is made just like me, simple.

Print this with whatever settings you like. I printed at 100% infill because I forgot to change it. Best printed on it's side with no supports, worked just fine. As you can see it fit perfectly behind the axis stepper.

A side note: When I print bolt holes I always make them smaller so I can drill them out for a more snug fit. So I suggest a nice sharp 4mm drill bit OR jump on your slicer and make them bigger there. It's your world.

extra bits needed: M4x10 x 2 T-Nut x 2 Cable Ties x as many as you like.
