My version stands about 12 ½ inches tall and hold an 8 inch knife.
PLA
0.2 Layer height
No supports
20% Infill (Increase infill on poles to help better support weight)
Spacers are so the knife doesn't get stuck to magnets and makes it easier to remove from stand. You can make them larger if you want to make it even easier.
I will attach step files so you may adjust it to fit different sized blades
Stand was designed to these magnets: https://a.co/d/j4aahtJ
NOTE: DO NOT put this near any electronics or other items that may be affected by magnets. The ones that are linked are extremely strong. Do not put the magnets near each other or they will also stick together and break.
