Simple cable guides for 2020 aluminum profile (6mm groove). Closed or open loop. Fast printing standing up in vase mode. Very strong through. The model is 100mm long so you can adjust Z proportion to get the length you need.
Same principle and same printing speed as my 10mn Led Strip Rail for 2020 profile, https://www.thingiverse.com/thing:2575322
and my 10mn cable clip for 2020 profile.
Tested and approved, enjoy !
Prusa I3, Tarantula, CoreXY, FLSun Delta.
Optimized for 0.5 nozzle but any lower size will do. Print standing up. I use no skirt, but if your bed adhesion is not optimal, you probably want to use one. The part genuine length is 100mm, but you can adjust the Z proportion to get the length you need. For example 20% for a 20mm tall guide or 150% for a 150mm tall one.
