I like my filament wall shelves/rack, the only thing that was missing for my need was a system to keep the filament weel on the spools, to avoid filament tangle while printing.

I don't like filament clips directly on the spool. I wanted a quick and easy way to store my spools.

However, after many iterations and test, I finally found a design that meet my needs, I designed a clip that directly fit on the shelves (1in / 25mm wood dowels).

Easy to print, easy to install, very convenient to use. If you want another size just let me know, I'll do it with pleasure.

Enjoy!
