Small tractor with freely rotating wheels printed in just one piece. It is printed in the "on the side" position so no need to add supports. For a functional print, you need to have the first layer and flow properly calibrated (to prevent the wheels from sticking to the chassis). When removing from the backing, it is advisable to wait for the backing to cool and remove the print carefully due to possible breakage of small parts.
