This is filament holder from aluminium pipe. Its derived from Thingiverse 5488992 which use wooden rod. My version use 25 mm /2mm wall thickness pipe.
I Put some extensions to it, in my room I have some funny areas which are 57 cm wide so this solution with 50 cm pipes do it right (I buy 2m pipe and cut it to four pieces)
Print two parts, left and right, mirror them. They are not identical so you just can't copy it.
I print it PETG, 6 wall thickness and 25% infill, no support required.
If you want made it even sturdier, there is hole trough holders so you can use 10mm threaded rod and couple nuts with washers.
