Extremely Strong Filament Rack

This is a filament rack designed for 1kg filament spools, or spools of anything that are 200mm(~8in) in diameter. To test it for the optimal shape, I used the Finite Element Analysis inside of fusion, to come up with this design. Based on the tests in fusion each one can handle 80lbs of load safely in normal PLA, however, that does not factor in things like layer adhesion, or line direction, which is nearly impossible to stimulate. The tests say two can hold 160lbs of weight, or 70 spools of filament, making the maximum “safe” spacing 17.5 feet apart. But do not do that as the FEA does not account for layer adhesion, line direction, or anything else like that. I recommend spacing them no more than 5ft apart. Drill them into the nearest stud. In the US studs are spaced either 16 inches apart, or 24 inches apart on normal walls. On openings, there is 3 inches of wood horizontally to the frame opening by law. You can find these studs by using a magnet to find the screws that go into it, u
