This is a spool holder project I have been playing around with for awhile. I had my smaller spools hanging from the rafters using an old Ender 3 spool holder, but I needed something a lot larger to hold my 5Kg spools up there. I found a small spool holder on Thingiverse and I have scaled/modified the spool holder, making it much larger and wider to fit a variety of spool sizes and weights.

The spool holder can handle 14" diameter spools, possibly up to 10Kg. Use cubic infil in order to have enough bar strength. Filament tends to loop off the side of new spools. I have added a runout switch mount in order to keep the filament centered. I will add that model in another listing. 

I have added two center rods. The 28mm rod is for Zyltech 5Kg spools, all other spools can use the 30mm rod.
