This is my original design from Cults that I am posting here.
2021/02/12 - Designed a stand to let me use a 5 kg spool. Now, I printed this on an Ender 6, with a 290mm*290mm build plate. It will not fit on an Ender 5 or 3's 235*235.
You'll need to print two of each file. In addition, it is designed to use 4 M5*12 screws and nuts to hold it together. I use a ~8" * 1/2" electrical conduit to hold the spool up. (I intended to use 3/4", but neglected OD when designing. 3/4" wood dowel should work, channel is 20mm wide.
Spool in picture is 160mm wide and 300mm in diameter. Stand has clearance in both dimensions if your roll is a bit bigger.
2023/02/15 - Last week, someone at work came into the area where I use this for myself and asked if I could do something similar for a roll of labels for a printer somewhere else in the building. The short strut was born of this request, it narrows the inner width to 5", you'll need a rod/dowel just under 6", same hardware.
