A magnetic K Cup holder that can be attached to any magnetic surface most likely the side of a fridge which is where mine is currently located. They can be stacked on top of each other and will attach with magnets. I have updated the design with version 2.0 that includes friction fit magnet holes, plus 2 additional posts for the magnets for improved attraction to the metal surface.
Version 2.0
For version 2.0, the magnet holes are specific for 10mm x 3mm magnets. The magnets fit into the holes tight so no glue should be needed. If you would like to glue the magnets I would recommend using E6000 glue to hold my magnets. These were the specific magnets that I purchased:

Version 1.0
The spacing between the magnet stands and the backing is 3mm. The round place holders are 18.5mm round. The specific magnets I used are 18mm x 3mm which can be purchased here:

The magnets overhang a little bit on the stands, but hold the model just fine.
This is meant to be printed with the front face down without supports. I printed this with a .6 mm nozzle with .3mm layer height in Matte PLA.
