customizable spool + tool

thingiverse

I required some spools for prototyping cables within my lab. I have different sized cables, and since I wanted all my spools to be the same (or at least identical), I was unable to find any design that met my requirements. I created a 10mm and a 15mm spool part, as well as a 10mm spacer that is optional for the design. This allows you to customize the spool from 20mm in width, and upwards in 5mm increments. There are two holes in the center wall of the spools, one 2mm and one 4mm, making it easy to wind cable from AWG14 down to AWG30 or multiple conductors. Two 10mm spool parts can easily hold 50m of AWG24. I also found that winding cable onto spools was extremely challenging, so I created a tool to mount into a screwdriver. The connector on the tool is a standard 1/4" hex tool bit. Although I'm not sure if it's necessary, I am slightly paranoid, and I would be really annoyed if the bit broke off in my screwdriver, so I installed an M3 screw all the way through the bit. To use, print two of the spool parts (either two of the same or one of each), and optionally the spacer. When printed, screw the parts together with M3 screws. The spool parts should print without support material, but the spacer and spool tool will require supported material. P.S. Sorry for the misunderstanding; by "customizable," I meant that the design is adjustable rather than using an easy-to-use script.
