Tevo Tarantula Rail Mount Wire Clips - 3 Sizes - Small, Medium, Large by emanuelbucsa on Thingiverse: https://www.thingiverse.com/thing:1935014

Summary:
 UPDATE: Large wire clip updated with added strength! I recently got the Tevo Tarantula 3D printer, but I wanted to customize some of the cable management to my liking, so I created these 3 wire clips. The small one has an internal diameter of 7.5mm, the medium one has an internal diameter of 10mm and the large one measures 15mm for the internal diameter.I included the separate .stl files for each piece, along with the sketchup file containing all three. I also attached a few pictures of the wire clips "in action". They are snap-in wire clips, so all you have to do is ... snap them in. The small and the medium one sit quite well on the rail, the large one is a bit wobbly, but that one's reserved for a lot of wires that need to pass through it.
