A walker:bot to put your micro:bit in with servo motors and a servo light board. You have to tweak the code quite a lot, to make it work. I glued the legs to the board, so it was a lot more steady. https://makecode.microbit.org/77172-04066-09949-18552

Print the legs, glue the to the body. Put in a servo light motor board, use 2 servo's and connect them to the body. This is my code: https://makecode.microbit.org/77172-04066-09949-18552
