I’ve released a thing on Thingiverse!
I needed a general spool for holding any sorts of wire for around the house, I’m yet to run out of any in my 3D filament spools, so I had to make my own!
This seems to fit perfectly on a floor shelf I bought from kmart along with my other existing filament spools, saving space on my already cramped home maker space (I’m sure a lot of you can relate)
Created in Fusion360, means that most of the dimensions are modifiable to suit different wire widths / lengths.
Here is some of the detail of the spool core, I've designed it so not have overlapping tabs, to preserve the strength of the print.
