The 3D printing process requires a supporting frame during printing, see below left. The
printed part is cut from the frame using flush cutters and this sometimes leaves small bumps on the
part. Use a knife with a sharp new blade to cut away the bumps. When trimming bumps off the
wheels you should place the wheel on a flat surface as shown below on the right. Putting too much
stress on the wheel can cause the axle to break. For bumps on the cab body, sanding is
recommended.

After cleaning up the bumps, paint the chassis flat black. Once this has dried paint the wheel
hubs, fuel tank, etc., as shown below.
