customizable spool + tool

thingiverse

I needed some spools for prototyping cables in my lab. I have different size cables, and since I would like all my spools to be the same (or at least alike), I could not find any desing that met my requirement. I made a 10mm and a 15mm spool part, and a 10mm spacer that is optional for the design. This allows you to customize the spool from 20mm in width, and upwards in 5mm steps. There are two holes in the center wall in the spools, one 2mm and one 4mm, to make it easy to wind cable from awg14 down to awg30 or multiple conductors. Two 10mm spool parts easily holds 50m of awg24. And finally I found it was really borrowing to wind cable on spools, so I made a tool to mount in a screw driver. The connector on the tool is a standart 1/4" hex tool bit. I do not know is it was really necessary, but I am slightly paranoid, and I would be really annoyed if the bit broke off in my screwdriver, so I fitted a m3 screw all the way through the bit. To use, print two of the spool part (either two of the same, or one of each), and optionally the spacer. When printed, screw to parst together with m3 screws. The spool parts should print without support material, but the spacer and spool tool will require supporte material. ps Sorry, by "customizable" in this case i did not mean "scad eazy to use script".
