===UPDATE December 2023
Added v3 that has a slightly taller edge for the holders to slide into. Also added a version for just two holders wide (2 slots)
===ORIGINAL POST
I loved the design, and printed 3 of the (K-cup Holder by Jdalycache) but didn't want the them just sitting loose on the countertop, so I made this tray or baseplate for them to sit in.
