Parametric wire spool holder that mounts to your pegboard. Highly customizable so it can fit any wire spool or pegboard (including IKEA SKADIS boards). Includes hooks for both styles of pegboard. I recommend printing the wire grip block with the hole through it in TPU as this allows the wire to wedge into the hole in the front bar more easily and provides a strong grip on the wire to keep it in place. I used PETG for everything else but PLA would probably work unless your wire spools are quite heavy.

Hope some people find this useful!
