Compact and strong fillament spool holder, designed for spools that are up to 300mm in diameter.
This spool holder is designed for a big 2kg spool. It can also be used to hold standard and smaller spools, but can also fit a spool that is as big as 300mm in diameter and 102mm in width.
It is designed to be easily disassembled when no longer needed.
The roller ensures that there is little effort required for the extruder to pull the fillament even when the spool is full.
Unfortunately, the "Stand" part needs a tiny bit of support, all other parts do not require any support.
I found the structure to be very stable. The stand in pictures was printed in PETG. I have no idea how this would transfer to PLA, but I imagine it should work just fine.
