My attempt at securing the most niche model in the organization contest.
This holder is designed to hold all five marking pens used by beekeepers to mark their queens. Five markers are used in a rotating five year sequence. The holder works by allowing access to only one pen at a time. Each slot is labeled with the year-ending number that corresponds with that particular color.
This is very much a work in progress so print at your own risk. My intent is to have this print without the need for supports.
I borrowed the ratcheting mechanism from the allen key ratchet designed by Reivax found here: https://www.thingiverse.com/thing:4489865
Print vertically. No supports should be necessary. 3mf is set up for multi-material to highlight the lettering.
