DEVVIS robot mower H750 front wheel washers

thingiverse

So my DEVVIS H750T started to behave weird - turned, stopped, turned, stopped and didin't move as normal. Turns out the front wheel uses plastic bearings and the washer that should keep the smug out, doesn't do it's job. So the wheel was loose and slanted enough to obstruct the movement of wheel. So I dissasmbled the wheel and changed bearings to sealed steel ones (12x28x8) and this washer is made to prevent smug getting in the wheel that easy. It's designed by my printers error and might need fine tuning for other printers. I printed it in PETG, 25 gyroid infill and that's it. Works wonderfully. PS: DEVVIS robots are branded with other names as well, so this might be used on anyother brand mowers that use the same platform.
