Switched to the bearing-based spool holder from AngryHulk for heavier spools, but I found that small diameter spools would fit on the larger spindle. So I created a bearing-less version just for tiny 250g spools since they don't really need the bearings.
This essentially just takes the quick change adapter and the spindle parts of the original and fuses them into a single piece.
Print it vertically with the quick change adapter at the bottom. I recommend supports for over hangs 80° or greater and only where touching the base plate (just to get a clean print on the adpater).
