Clamp on Filament Rack Bracket

I designed this bracket to be able to clamp to a surface in place of being permanently attached to it. In my case, a steel I beam, but I made the clamp compatible with a thickness up to 25mm (1"). You could clamp it to an already existing shelf if needed. The screw does need to be glued together; I left a 4mm hole in the center if you wanted to fill it with epoxy or add a metal rod for strength. The screw is a M14x2 and I would recommend running a tap through the threads in the bracket body for a smoother experience. You will require 25mm (1") dowels to make this into a proper rack. I have 4 brackets over a 2 meter (6.5') span and they are holding just fine. Printed in BBL PETG HF.
