Remix of @Biskup's “Universal Spool Holder” to attach to wire rack systems.

Base redesigned to snap onto wire rack shelves. For shelves with ~2.8-3mm OD wires that are perpendicular to the wall and front wire diameter ~7.8-8mm. Back tabs require some force to snap onto wire for a secure hold.

Wire styles tested:

Tabs/fingers unchanged from @Biskup's original version. Adjust print settings to get the look you prefer, shown with 1 bottom layer and honeycomb infill. They fit best when using a textured build plate.

Use slicer to edit the tag text as needed or make solid (Font used in photos: Pervitina Dex by deFharo). Tags are removable with small access hole from the inside.

Minor cleanup may be required on top layer of tag opening with snippers or razor to remove overhang peel for tag to snap flush.

Increase wall loops and decrease speed if printing silk filament.
