This is my first model for 3D printing and third model printed ever (first was test model, second was first version of Piggy after wich I made some little fixes)
Model is 4cm with flattened base.
No supports should be needed.
There was few bad faces on back.
Made better angle of faces near base (it should print better now)
Logo is more visible (if you don't want it you can lower model in slicer, just up to the tail)
Addons for Piggy:
Helmet, beanie, trousers etc.
You can print the piggy even without any infill (at least with 4cm print).
