Wooden trike electric set

Small modification of wooden trike for youngest :)

I have used old cheap battery drill motor with planetary gear. It is rather typical so probably almost all cheap battery drills have the same one.
I have added stp files too, for easy modification.

Every element need to be printed in one piece.
