This is heavily inspired by the acrylic Anycubic spool holder I got with my first printer and needed more for my toolchanger. I like the design because of it’s simplicity and that the spools stay in place while printing.
So I made this for spools of up to 200mm diameter and 80mm or the wider for up to 120mm wide spools.
If you print the pipe then you will not need any hardware either.
