Filament Storage Mounts

Files are for two versions of brackets that I mounted to an old Ikea desk to store filament and 3d printing items. The shelves are two pieces of 1 1/4" x 1 1/4" pine from a 2x4. I like how everything sits at a 45 degree angle for easy storage and removal. V2 of the file might be more appropriate if using a 1 1/4" dowel. I just couldn't find a dowel long enough for this table or would have gone that route. It's currently holding 11 rolls of filament, so seems to be strong enough. The holes in the bracket are 0.2" with a 0.5" counterbore for a drywall or any appropriate pan head screw.
