Its maybe not super ideal for the flash and Lidar sensor. But so far there is no issue for me.
I have some more redesigns ideas for this, but this is what I got for the moment.
Turn the print 180 degrees (holes on the bed).
Put supports on. With good settings you will get a clean surface and easy to remove.
I used a modifier in PrusaSlicer so I got one wall on first layer, just to get a smooth look.
The author remixed this model.
More detailed cover for the lens.
