About this 3D model
Remixed version of JoerT 's Insulin Holder to accommodate 6x3 magnets. These might push fit depending on calibration, however, it's usually easier to put a dab of superglue under them, just watch out for the polarity. There are multiple bodies in the STEP and STL files. Split them up before printing. I included separate TOP and BOTTOM STL files for your convenience.
