I made this to complement my collection of Tiny Wheels by "agepbiz".

This is designed to be printed without any supports, though you might want to use a raft.
Let me know what you think of version 2, I added a movable bucket.
If your slicer is having issues with the file, you can use V2 repaired. The mesh is messier, but it is a water-type mesh.
I'd love to see pictures of your prints!
