Filament Shelf - 2020 Aluminum Extrusion loosely based on RepRack

Basically a remake of RepRack's Filament Shelf, but with 2020 Aluminum Extrusion. Choose either the over shelf bracket (bracket can act as book end), or the under shelf bracket to give more room on the shelf, depending on preferred style. Also, you can choose between the single reinforcement, or the full reinforcement, or none at all if you feel the bracket is enough. The french cleat is done at a 45 degree angle and 20mm deep, so should be easy to use wood instead of the printed one, if desired. I printed it with PETG with 6 walls and 0.8 nozzle, but I'm sure that is overkill. Use your best judgement and overkill is always preferred for a shelf. See original for BOM (screws), and use whatever length of 2020 aluminum extrusion you like. The reinforcement piece can take a m5 bolt on the bottom with a T-nut to help keep things from moving. Please make sure to screw into studs, as I'm uncertain how well drywall anchors will hold with too much filament. Most studs are 16" apart, so as per most shelving standards, you should do at least every other stud if filled with filament. Even more so if you wish to add more weight on shelves. Again, use your best judgement.
