You need 3 brass M4 inserts and generic 35x18mm titanium coated blades compatible with husqvarna. Also 4 M4 bolts (20-25mm) to mount the disc.
I print the base in PETG, though PLA will probably work too. The cover ideally in polycarbonate, although PETG also works.
I use 20% infill and 3 perimeters at 0.3mm.
