Chicken Egg Scale

To make this egg scale work you have to use washers as counter weights on the back arm and the bottom of the front arm. There are screw holes for both locations. There are 16 washers on the back arm and two smaller washers on the front arm. Hopefully you can see from the pics. It might take some fiddling around to get it right.

You'll need some superglue to glue the base together, and glue the body to the base with the support brackets. Ensure the holes for the M3 bolts are large enough to give a free smooth pivot.

Also, I had to reduce size to 75% in Cura to get this to print on my print bed. That's the right size anyways. I designed it a little too big, but reducing by 25% it turns out perfect.

No supports are needed when printing if you place the parts just right.
