Remodeled the original CR-100 spoolholder to accept larger diameter spools. Print with support and the smaller part pointing down. Use enough shells and infill so the link between both parts is strong enough (small connecting area!). The slopes on the large part to hold the spool in place don't need support.
I suggest to print 4 of the m3 standoffs aswell and move the whole extruder assembly ~5mm outwards so the filament doesn't rub against the spool wall under tension. See last picture.
