Duplo 4 wheel cart 2x6 brick

2 by 6 duplo brick with 4 peg for wheels with wheels, really tight. Printed with PLA 100% infill. Wheels should be drilled out with 10 or 10.5 mm bore. This thing might be work in progress.

Small update on this one: Kid still have not broken it so it should be sturdy enough, printed in PLA.
