Spool Wall Mount, Fast print

I was looking for a spool wall holder so that I can feed TPU directly into the extruder.Non of the available models were really making good use of the anisotropic material behavior of filament printed parts and took over two hours to print.So I designed my own one which only takes 50 minutes to print in PETG, makes good use of the material behavior and is able to hold over 5 kg (see last photo, tested with a 5kg dumbell weight).
