MakerGear M2 Printer Spool Holder -- 3/4" End Caps

myminifactory

The MakerGear M2's filament spool mount functions perfectly when paired with thick-edge spools like those used by MakerGear itself. For other types of spools, a modification suggested on Thingiverse (thing:37210) provides a significant improvement and can even accommodate easy switching between different spools. However, MatterHackers and some other filament suppliers often utilize spools featuring extremely small core holes, rendering the rod proposed in Thing 37210 ineffective for fitting through. To prevent this issue, a simple push-on end cap has been designed with an interior that securely grasps a standard 3/4" wooden dowel as depicted. Without these straightforward end caps, uneven winding of certain spools can cause the dowel to become dislodged from its proper position within the spool, resulting in undesirable consequences.
