This spool holder is meant for the interlocking type spool holders and reduces the overall height of the machine by 2in. This was achieved be lowering the angle of the arm, and shortening it just a bit. It is perfect for those who want to maximize their shelf space and in my case, I want to put a stone paver underneath to reduce noise. Print with supports to help the locking tabs printout properly, and 10% infill is plenty for most holders.
