Homeracker Spool Holder

I could not find anything to hold my active spools for homeracker, so i made it. It is designed for bambulab 1kg spools. Warning: the "Spool Holder - side pin" is experimental. since it is designed to be printed flat on the bed, it is to slim and the ball bearing is slightly wobbly. I uploaded it just as reference or idea for someone smarter to improve. the hole in the filament guides might be a b it tight, i had to widen it a bit, but i did not want the ptfe tube to fall out easily. missing:a nice parameterizable (i have no freaking idea how to do that) silicagel box for above the spools. Maybe some kind of drawer system for a container printed with PC, so you can put the whole container in the oven
