I looked on Thingiverse for some sort of wire jumper storage solution, but there wasn't one -- so here's my take on it! This is a tough print if you have print lifting issues, but the solution to that is to apply glue stick to the bed. I'm not joking. Mine's purple. I changed the file to accommodate an extra wire colour from the one shown. This is one of those "gee I wish I had a laser cutter" projects. I will soon be uploading a "single wire" version for weird jumpers like the extra long ones. Edit: I refined my jumper holder into a jumper tree! All you need is 8mm rod (5/16" ish) and you too can make the jumper tree! I will likely further refine this, but I will upload the final versions of files.Printed flat, 0.3mm layer height in ABS. Lifting can be limited with glue stick. I had to drill the parts out to 8mm, which gave a nice press fit. I included the SolidWorks 2010 files just in case you want to make your own edits, but be warned--my feature tree is abysmal!
