Robot Lawn Mower front wheel / support wheel

I use an old tianchen lawn mower. After lots of customizations like new main board, new software (visit www.ardumower.de) and new blade disks, I found that the robot is really loud when wheels roll over stones like small paths.

The main reason for this horrible sound are the rock hard front wheels and the bad bearings of them.

Because I had some 2K silicone laying around, I created this silicone mold to create new, soft wheels with new bearings which make really no noise. The wheels fits perfect on my Tianchen mower and might fit on others too.

The picture above shows two wheels made of silicone (yes, the red one is also silicone)

You need to print

1x Top mold
1x Bottom mold
2x inner part (kern)

You need some additional things:

1. approx. 80g of 2k silicone, I ordered mine at www.trollfactory.de
2. two bearings of type 6000 ZZ
3. Screws M3 to combine the inner parts to one part (screws will become part of wheel)
4. Screws or zip ties to close the mold (can be reused later)
5. syringe, mixing pot, and some other household stuff
