track pad for lego tracks

cults3d

Some toy caterpillars don't stick to the ground because it's too hard for their plastic surface. So, I created a TPU skate with an adjustable clamp that clicks onto the tracks (as many skates as there are tracks). Be cautious when using this design, as the "heads" of attachment only fit one way and won't work if flipped around. I tested this solution on fake Lego Technic parts sourced from China. Fortunately, it also works seamlessly with some genuine Lego Technic components. I'd like to apologize upfront if my free designs are exploited by individuals who resell them as their own.
