Big Filament spool stand

thingiverse

I had trouble using a large 2.5kg spool because it wouldn't fit on any holder I owned. Furthermore, putting it on ball-bearing guided pipes didn't work out since the spool's thicker middle section prevented it from fitting snugly onto the outer shelf. So, I rapidly constructed a stand for it. It has an open top for easy mounting and dismounting, assuming that the weight of the spool would be sufficient to keep it safely in place. If not, maybe building a clamp that can be mounted on top and some screw holes for the bottom part might be necessary. The alloy tube used is from the Qidi printer filament holder; however, you could utilize whatever materials are available or even 3D print one if needed. To minimize rolling resistance, consider adding a spool spacer, which I have uploaded here: https://www.thingiverse.com/thing:4286502
