Filament spool holder - Wall mount bracket

I designed these so that you can slide some wood into them, as shown in pictures. They are sized such that spools of filament can rest on them. Cleans up your space for other things! Step files are included so you can easily change the dimensions for your specific material. Use for any width. Supports upto 15kg each pair!

Suggestions:
Print in flat orientation.
Separate prints for left and right, which should be printed flat on build plate.
Suggest for mounting on wall studs to decrease risk of falling.
2 or more wall layers, 10% or higher infill, grid or similar.
No supports required.
Model supplied requires wood profile 27.5mm x 17.5mm rectangle or similar - Can be easily changed with CAD software.
