Summary

Printed vertically with brims and supports at 20% infill on Super Quality on my Ender 3 Pro.

Remix of the design by rbross. I split the tank and then added a hole in each section to fit these magnets: https://a.co/d/aTny11l

Be careful about the orientation of the magnets, I mark the outside faces of a pair with a sharpie to keep track of which faces should be glued down.
