I knew this principle from adhesive foam tape guiding. Thought it would be useful for something else. So I applied this technique for the cable guidance of my eV-charger cable.
I designed mainly two types: one for ø12mm and one for ø20mm.
Each main corpus consists of two (here: black) main bodies and four (yellow) rollers. For the rest you need two M3x20 screws plus nut and four ø3mmx25mm dowel pins for the ø20mm part. The ø12mm part needs four self tapping screws and four ø3x20mm dowel pins.
The assembly can be done when the cable is already inserted. Herefore, you pre-assemble three rollers with dowels, put the cable in place and close it. The open gaps will be closed by the counter parts.
Additionally I added a ring that takes the cable guide and keeps it in place by a M3x10 screw with nut.
A M6 screw can be screwed in and the hole with the M6 nut fixes the complete assembly. In my case I could used some brackets to fix those with wood-screws on my wood beams.
Printed in PLA on my Prusa and Bambu printers. The rind I printed in PETG, hope this is more sustainable and less brittle than PLA.
I am sure, once you printed one or two versions you will be able to fugure out for which purpose you can apply it. Good luck!
