Wall Mounted Spool Holder

Spool holder that you can mount on the wall to store or use filliment from. Was designed around Maker Geeks 1KG spools which have a slightly smaller hole than most so the spool holder on my printer was causing alot of friction and under extrusion. Works fine with "normal" sized spools too but .5KG spools may not fit unless they were made specifically so they would fit on a larger spool holder. The weird corner seen in the picture isn't part of the design, i was just using really cheap filament (this uses around 250g) and it peeled up from the bed a little. threads are big enough so you can print the whole thing at .2mm or probably even .25. printed this with 15% infill and 4 shells, but its way stronger than it needs to be so 3 shells and 10% infill should be more than enough. printed with the left side (side seen in picture) parallel to the bed and with supports.
