I made it with original setting (15% infill) and 0.15mm layer height (I think it perfect with 0.20mm LH too) as you can see in the attached files.

It's easy to assemble, as the GIFs show. The connectors work perfectly with the size of 100%, I haven't tried in another size yet.

Entire pig:

You can print the it with supports or you can cut it into separate objects as you want.

Body:

Place it to the bottom and print whit supports (use normal supports instead of organic).

It isn't very easy to remove the support you should use a scalpel and a mini screwdriver.

Head:

Place it to the bottom and print whit supports (here you can use organic too).
 

You have to print one body, one head, two leg and two leg2.
