Updated with two more variations. Versions 2 and 3 shouldn't need support if your printer is dialed in for proper bridging.

An upright base for spooled kitchen twine or cotton thread. Tapered base allows for spools of different sizes from 10mm to 25mm. Upper arm allows thread to easily unspool and minimize tangles. Place it on a taller shelf and pull down for easy one hand usage.

Solidworks part included so you can modify for your own purposes.
