This is a fully customizable spool centre for filament spools designed in Openscad.
The source is here too so feel free to poke around!

There are several settings you can customise to generate the spool holder you need.
All dimensions are in mm.

Spool Diameter
The size of the hole in your spool

Spool Width
The width of the spool holder you want to create

Shaft Diameter
The diameter of the threaded shaft you will fit the spool onto.

Hub Length
The length of the centre hub for the spool. If the shaft is shorter than the width of the filament spool, the centre can be recessed to allow you to fit spools that are wider than the shaft.

Hub Diameter
The diameter of the centre hub of the spool holder. Make it large enough to contain the hole for the threaded shaft
