Rotating wheel base for Gardena R40Li and similar models

Hey guys! 

I once sold those on the net, but i think it's the right thing to give it out for free now. 
If you've got problems with the robomower pulling out grass while rotating, this rotating wheel fixes it. 

You only need: 
- a similar wheel as on the picture (think it's 4-5cm in wheeldiameter) with a rotating circular base. 
-M8 Screw (i used hexscrews)
- 2x M8 washer
- 1x M8 springwasher (optional, but nice to have) 
- 1x M8 selflocking nut

You have to unscrew the original 3rd wheel of your mower and reuse the torx screws with the new adapter. 

Part is used and approved for 3 years straight. Print in PETG/ASA for maximum strength.

Attention:
The picture used is not the actual model, it was modified and used as reference. So you're able to see which wheel should be used.

Happy mowing!
