This is a knife holder inspired by MKB 10 ADDA from Catler.

It uses 28x neodymium magnets with 10 mm diameter.

Use

• 1 mm height for 1 kg magnetic power per slot
• 2 mm height for 2 kg magnetic power per slot (for extra heavy knifes)
• weaker (smaller) magnets for lighter knives

It's been hollowed out to save a little filament and it is advices to fill the inside with sand or something similar to make it heavier. The cap is advised to be glued when filled.

Update: I've added in-one-piece model. Please, verify your knives are heavy enough to act as added weight or use weaker magnets (but strong enough to hold your knives though), so the holder doesn't lift when you are removing a knife.

Notes

If you want smoother top finish, use adaptive layer height (from layer 753 upwards (767 for in-one-piece model)).

Walls are 1.35 mm wide so use 3 perimeters with 0.45 mm extrusion.

Body part should fit on 230 mm x 217 mm bed (such as Ender 3).
