This piggy bank has two separate rooms to insert coins and it’s balancing based on which side you enter more coins. As I like fast and easy to print designs, This one is fast and uses very little filament.

• Uses only one 608 bearing
• The print profile contains 2 plates: one with black filament parts and one with the white part.
• Contains 4 easy and fast to print parts, without supports.
• The front parts (yin and yang) are separate objects, to be easier and faster to print without changing colors.
• you can insert one coin to the smaller bottom rooms, to equilibrate and stabilize it in the right position.
• carefully insert the yin and yang into the bearing (to not brake it)

Update 02.12.2023:

• added a file with all the parts, upscaled at 150% and modified to still use a 608 bearing. Even if I tried to take into consideration tolerances, this is not tested yet. Please use it only if you really want it this big.
