SMARS - a version of the fuselage with wheels mounted on 608ZZ bearings such as for a roller skate, plus wheels, rims and tires.When printing the fuselage, it is necessary to support under the mounts for the bearings. These bearing mounts may require careful use of a file or sandpaper before attaching the bearings. Contrary to fears, the bearings hold firmly. If they loosen too much, a small amount of droplet glue can be applied to the mounts and the bearing put on. Such glue does not adhere firmly to the metal, so the bearing can be removed after it dries.The wheels rest on the bearings on the axles protruding from the frame, rather than directly on the motors, so the motors run comfortably. Two motors are enough, but you can also give 4, I gave two. The wheel consists of the bearing, the attachment of the bearing to the motor axle and to the wheel housing, a thin masking washer, the rim and the actual wheel housing. I printed the wheel components from PLA, PET, ASA. The hull of the SMARS is mostly made of PLA.The hole on the side is left for connecting a micro USB cable for charging a 9v battery. You should be able to find the rest of the components somewhere under the SMARS heading on printables or on thingiverse.Remember to print the tire with 0% fill!!! Otherwise it will be too hard and cannot be applied. I used Noctuo grip flexible filament to print the tire. You can also use standard tracks.To remove parts from inside the wheel housing, I included a two-piece extruder. This makes it easier to replace the wheel parts.Original design is here:https://www.thingiverse.com/thing:2662828
