Piggy bank

cylinder piggy bank with capsule shape interior. first design not sure how the print will be due to the interior still new to cad design. I made it to where the plug does not need supports! please leave any helpful tips on designing much appreciation.

fixed plug issue. didn't realize the plug had more of hex shape so both the plug and hole is fixed.
