Here is a cute penguin model that can be painted and used with the AMS!
I have printed the model with entirely 15% infill and the penguin does stand up, but is easily tipped backwards. I recommend using a modifier to change the front half infill to 25% and keep the rear half at 15% to correct its balance. I provided a profile which already contains this modifier.
Supports are required for this model! I also recommend using fuzzy skin for the ball at the top of the penguin's hat.
The author marked this model as their own original creation.
