Ống heo Yin & Yang – cân bằng 2 bên

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. The test model, which works perfectly is printed with 5% infill, 2 walls, 2 bottom layers, 3 top layers. 
 

• Uses only one 608 bearing
• 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)
