T Spool Holder for Prusa printers

thingiverse

If you like Prusa's T-bar spool holder design but didn't get one, you can print your own substitute. The DIY version won't be as rigid as the injection-molded original, but it should work fine. The design prints in four parts that can be glued together. There's a variant for the arms with higher torsional stiffness, but it might look less appealing - a matter of personal taste. It's suggested to use full honeycomb infill for the arms and avoid using PLA as the material will slowly creep under load. My own version is printed in ASA. If you want to customize or improve the design, there's also a step file available.
