Wheel, axle and bottom plate for Scooby Pool Robot

My Scooby Pool Robot made black lines on the sides of my pool and the bottom plate was broken so I designed some new ones and printed it in white PETG.

I printed it all with 0.2 mm layer height with standard setting and only the axle needs 100% infill and support as it has to be printed horizontally to have strength, the support has to be scraped off afterwords though.

Place the axle in the wheel and it is ready. The plate can be attached by bending it slightly, I uploaded the files as stl and 3mf, let my know if more explaining is required.
