I had issues printing this with a 0.6 nozzle without a brim. The two small legs on the corner were always breaking of and destroyed the whole print.
I figured out the do not have any use for me, so I removed them and made the print a little easier.

I also adjusted the wheels, I found no need and having them rounded on the outside, but having a little cone on the inside makes life much easier.

Works now without a brim, 0.4 and 0.6 nozzle in draft and speed settings with PrusaSlicer and my Prusa
