Husqvarna 415x Traction wheels

My Automower 415x had trouble with my lawn, so I started experimenting with wheel designs. I went through several iterations and this design seems to work best. The main problem I had printing is the size - these wheels are too big to print on a Prusa, so I got my hands on a Bambu. If there is interest, I can modify these to print on a Pursa by reducing the outside diameter, you can't simply scale them. You will need to mirror the second print to get the treads in the right orientation. 

You will need to add supports to print this. I've only experimented with PLA so far, ideally this gets printed with ASA to survive the outdoors. 

To install, pop the hub off the stock wheel, under it will be a large nut. Remove it and the wheel should come off. These should bolt right on.
