ID Tag Holder

At my work (chameleonusa.net) we offer custom laser engraved ID tags in different colors. To keep the colors separated I designed and printed this holder that allows us to quickly grab and engrave any design without having to rummage through baggies or bins.  This took 8 hours on an ender3, and I printed it with 20% infill. The larger files was designed first, but it would have taken too long to print, so I cut the height a bit. The trays have a slight slope to ensure the tags do not slide out.  Everything was designed in OnShape (free plan)
