Magnetic Holder for "CANARY" box cutter with STEP file

thingiverse

This thing is a magnetic holder designed specifically for a "CANARY" box cutter (https://www.amazon.com/CANARY-Corrugated-Cardboard-Cutter-Parallel/dp/B075FS764K/). It relies on five 8x3mm cylinder magnets that are carefully glued into the holes. Two of these magnets are set in deeper to provide added stability and help securely hold the cutter, but it's essential to orient the holder so gravity aids in keeping the tool firmly in place (not upside down where it would risk falling out). Using stronger neodymium magnets with this design is highly recommended (N52 if possible). I opted for them, and on my fridge, I can move the holder around freely without any concerns about it falling off easily. I printed this design at a resolution of 0.2mm with supports strategically placed everywhere, but utilized the Cura support blocker to eliminate supports from the area where the blade passes through. While leaving those supports in place poses no issues, there's also no problem printing without them (it would probably work just as well overall). It's equally possible to print this design with the open end facing upwards, which would not require any additional supports. I've included the STP file for easy remixing and modification.
