Really liked R4C3R's design (nice design, R4C3R) but I try to avoid using supports whenever possible and I think it needed a cap/insert to hold the wires in so I remodeled it so that you don't need to use supports and added a cap :)
NOTE: So that it doesn't get too confusing, in the next sentances, I will refer to this tool as the "loom tool" or the "loom" and the actual loom (that covers the wires) as "sleeving."
How it works (also see photo instructions):
- The cap slides into the main loom tool with the open section of the cap in line with the open section of the loom tool.
- Slide the wires in through the gab and then rotate the cap 180 degrees and slide it in till it looks like what's in the photo.
- With the wires locked in, pinch the handles on the loom tool (tightens around and holds the cap in place), put your sleeving over the nub of the loom tool, hold your wire and the sleeving and pull the loom tool - this will sleeve the cables in a snap.
- When you're finished sleeving the cables, pull out and rotate the cap 180 degrees again to where the open face is in line with the open face of the loom tool and slide the wire out.
Alternatively: you can do these same steps but instead of twisting the cap 180, you can insert the wire into the loom tool and then into the cap separately and then slide them together to lock the wires in place - same general concept but might be a little easier.
NOTES ON SCALE: I've included some pre-scaled versions ranging from 10-30 but if you need a specific size, just scale down the "Wire_Loom_100_Group" (or "100" version separate files [loom and cap]) to whatever size you need. For instance, if you need a 45, just set the scale of the 100 loom to 45.
NOTES ON PRINTING: None of it needs supports of any kind. I did infill %0 for the main parts/loom tools and infill %50 (fast honeycomb) for the caps - seems to work really well. NOTE: I'm using a 0.8mm nozzle and used 3 outer layers and 5 top and bottom layers with S3D's internal thin Wall Type set to "Allow Single Extrusion Fill" to fill small gaps.
PS. Be sure to check out the new facebook group called "3D Printing Useful Things!" - where you can find lots of other useful 3D prints :)
Instead of infill, you can just do 2-4 outer layers (or more or less depending on your nozzle size). Or you can do a little bit of infill if you want, totally up to you. Just do whatever makes it strong. I used 2 outer layers with a 0.8mm nozzle and 0% infill on the looms and 50% infill on the caps.
