Small (3cm) Piggy with a ring for keychain.
For Earring its better to print it smaller but use the size you want (resize it in slicer) , just remember that its better to print smaller ones with smaller nozzle.
60% size with 0,2 nozzle and 0,05-0,1 layer thickness looks good.
I will put a photo with earings later.
Original Piggy (4cm):
You can print few addons from here:
Scarf, band and trousers will work. Just resize to 75%.
You don't need any supports.
You can print it without infill but for more durability use maybe 15-30%.
