LUBA 2 mini AWD 800 replacement cutting disk It could fit other LUBA's and YUKA's. Please let me know if it does in the comments and share a pic :)

I recommend that you print with something more durable than PLA. It could be ABS, PETG or if you want extra hardness, Nylon Carbon Fiber (PA6-CF). Also, you have to use supports for the center hub, since it prints in the air.

I use 6x M3 brass inserts from AliExpress for blade holes. Currently, the hole is 5.8mm in diameter and mine fits perfectly (edit accordingly to your needs if your inserts don't fit).

Blades are also from AliExpress with screws included, but original blades fit too along with screws.

In your slicer, set walls to 4 for better sturdiness.

Test with caution! Especially if you print with PLA. I am not responsible for any damages or injuries. I recommend that when you mount it, test it in a safe area, if everything is okay, if it's not, then you can pick up the pieces (preferably not from grass).
