Bed strain relief for silicone spacer - Ender 3 Pro support cable hotbed

Description

A guide/cable support for the hotbed of a Creality Ender 3 or Ender 3 Pro 3D printer, designed as early as 2022. It is, of course, compatible with other brands or models of 3D printers, depending on the configuration.
Due to the pressure, the silicone spacer—even if it is cut shorter—eventually causes the original cable guide ring to expand, warp, and eventually break, as it is not at all suitable for this purpose.
The part I designed has no ring. The silicone leveling column can now deform without restriction.

It’s been installed for years now on my trusty old Ender 3 Pro—as a replacement for the broken original part—and I’ve never had any problems with leveling or with the cable’s tension and guidance.

This file was first shared in 2022 on Thingiverse, then on Cults. It has been downloaded thousands of times. Now, I’m posting it on Apiobi.com, still for free, because many makers—just like me—still own an Ender 3 Pro—a sort of mascot!
