Luba AWD - 6 Blades cutting disk & blades cover

As Mammotion's genuine cutting disk has been designed for injection molding, it is not optimized for 3D prints.

So, I redesigned it, with 3D printability in sight. It has 6 blades instead of 4 and a protection cover, to keep that all clean.

There is also a support, to help for the insertion of the Ruthex inserts.

• I printed all parts in PETG with a PLA interface layer on the cutting disk. The support released with no pain and the supported bottom surface is perfect.
• The cover can be srewed to the disk with M3x12 Chamfered screws. But this is optional, as the cover is self-centering and hold by the blade screws.
• There is a “Support tool” to maintain the disk flat when you insert the inserts. The threaded hole is to put a M5x8 Chamfered screw to act as a “depth stopper”

Update 2025-04-03:

Added STL for cover with 3 center screws, allowing to dismount the disc, without removing the cover and blades. 

Needed Parts:

• 12 x Ruthex M4x8.1 inserts for the blades screws
