Here's a simple spool support I created in Fusion 360. I didn't like how the spool holder would twist and sag, causing the filament reel to slide over and look like it would fall off. The support is easy to install and remove and keeps the spool holder more level. I've considered adding a TPU foot for better grip.

After printing the 2 parts, glue the small one to the larger piece to form a slot to capture the spool holder.

I've included the Fusion file, mod to your liking. I appreciate any comments to improve this design.

It's for the Vyper but may work for other printers too.

Use CA glue to attach the small piece to the top of the larger one to form a slot to capture the spool holder
