Ultimo v2 Lawn mower cutting disk with 6 knives for Ardumower Alfred (Fuxtec RB224, Güde GRR240)

I have designed a new knife disc for Alfred. I have been using it for 30 days now. In my tests, the cutting quality appears to be better, and the operational noise seems lower/more consistent.

The knife disc features openings for M4 nuts. Alternatively, the core hole of the bore can be drilled to size, and an M4 Ruhtex nut can be embedded. I have been using this variant since the beginning.

There is a V2 with an integrated knife holder, or the V2.1 version, for which 6 knife holders need to be printed. Since I consider the knife holder to be a wear part, I find this to be the better option.

Here are the data for comparison:

Original Knife Disc: 

Diameter without knives: 205 mm; Diameter with knives: 240 mm; Weight without knives: 149 grams; Weight with knives: 162 grams; Number of knives: 3 Knife; Offset: 0 mm

Ultimo Knife Disc v2:

Diameter without knives: unchanged; Diameter with knives: unchanged; Weight without knives: 187 grams at 80% filling; Weight with knives: 217 grams at 80% filling with Ruhtex M4 inserts and knives; Number of knives: 6; Offset: -2 mm (2 mm lower than the original)

Warning: Replacement at your own risk! Please keep in mind that it is essential for the disc to be stable. So, for all Bambulab owners, maintain cooling at a maximum of 15%, print speed at a maximum of 100%, and set the extrusion temperature high. I print PETG from the extruder at 260 °C, which ensures good layer adhesion.

I am open to tips and suggestions and can adjust the design or create multiple versions if desired.

I look forward to your feedback.
