This design does away with all the support that would be required if you made a single spool. Make two prints of the desired size. These two parts form a solid spool after aligning them and carefully bending on all 4 parts of the "stem" to get them to click in place.

Update Aug 17th 2020: added 4 more sizes. the name "HalfSpool_25i40f30w.stl" means that this spool has an inner diameter of 25mm, the outer Flange is 40mm (inner + flange + 2.8mm = diameter) and the total Width of the spool is 30mm.

I also added the Fusion360 file so you can change the parameters to suit your need. Change "InnerDiameter", "FlangeHeight" and "OverallThickness" to what you want.

Materials and methods

Tested with PETG, but should work fine with PLA and other materials too.
