My son asked me to make a little shopping cart, I made one
the wheels are rolling on a soft surface more difficult on hard surface.
easy to assemble print four wheel supports and two wheels
first fix the wheel supports on the cart with some glue look carefully at the bottom view picture to glue them in the right side is used cyanoacrylate (superglue)
then clip the wheel on the supports it's a bit hard to clip and after the wheel should roll easily.
don't use supports I tried once and they where very hard to remove, I changed design to not need supports
When you have printed the body you can remove the little three supports under the handle.
I have made them in the design to avoid huge support just for the handle.
