Filament Spool Chock

I needed a more narrow cradle for holding spools on my shelf so designed this. It has a nice little groove at the front so you can pull them forward to get them off the shelf, and are pretty quick to print. I print them 3x per plate. They work extremely well with Bambu filament, but also work with Sunlu and Elegoo. Polymaker does fit but it's a bit tight. I use these on a IKEA Billy shelf (40x28x202 cm) and they fit 5x across.
