I made this simple hand cart on the right for this months "Basic Bit" on my Patreon. And then I tried to make an advanced 3D version (on the left) as the flat wheels didn't impress me much. I am kind of proud that I was able to get this (esp the wheels) done with paper.
Here is a solo pic of the advanced one.
Ready to move your carts from dock to warehouse to ship and back!
