Filament Spool Holder

I tried using the dowel wall mount rack. When I started loading filament on the rack it started pulling it out of the wall about to fall. I decided to create a spool holder of my own. Each holder is mounted with two screws onto a piece of wood. I have tested it on Bambu, Eryone, and eSun filament spools. eSun spool fitament is tight but it does fit. You need about .5" between holders to release them with ease. 2 1" #6 drywall screws.
