I made two versions - they have opposite ear flipped.
Default model is 85x125x14mm, but you can downscale it as I did by my first try. The “result” how cookie should look like is rendered on the right side (the yellow one) of render photo.
Tested by printing down-scaled version (80% x, 80% y, 100% z), with 0.1mm layer.
Just look at those happy boys!
These boys are big!
