This is a customisable spool that I designed in OpenSCAD. You should be able to customise most aspects of the spool to fit your spooling needs.

Originally I designed a non-customisable spool to hold solder wire, but quickly figured out this would be a good opportunity to design a customisable part that I could use to organise/share other items in my workshop such as cables and thread.

The design splits it into two pieces so you don't need use supports. You can achieve a press/friction fit, but can also use glue. This dependent on the tolerances of your printer.

You can change the quality of the circle used for the outside flange to create a roll-resistant design like a hex/octagon.

To-do list:

• I will upload a diagram explaining all the parameters to help as a visual aid
• Change some wording with the customiser parameters
• Open up some parameters like spacing between the two parts
