Guy, I think I got these as either a free STL or I modified a free STL. I like the side supports, especially for a truck that'll go off-road.
This is one example of where print orientation is important. There are also other relatively minor issues with the print that are due to my wanting to rush the print and picking a resolution (50um) which is standard on most printers. This printer has much smaller pixels (and also rectangular) so in some situations, you get more obvious banding.
