Hi Shapies! I wanted to share with you the success (and failure) I've had so far printing the Roll-Back Racer (similar to the car in this blog). Let me mention, this is the second printing of the car. Unfortunately, the first car had a few problems as the gears in the middle were fused to the axle and the entire right side of the spring was fused to its housing. I made some minor changes and then uploaded/printed it again. Here is the new model! I modeled the car to fit pre-existing rubber L*GO tires (and it fits either thin low-profile tires or thick off-road tires). And, here it is without its tires. It looks kinda naked without them.
