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.
Hi! I've tried to resize it to 150% and modified the parts to still fit the 608 bearing. I've added a 3mf file with all the parts.
Please keep in mind this is not tested / printed. If you print it and works, please also add the profile you used!
If you find any tolerance problems, please let me know, and I can try to fix it.
Have a great weekend !
I put it together today. There is still a large gap of 14mm between the wheel and the bracket. Could you perhaps shorten it by 10mm? see photo. So there will be a gap with 4mm.
Then I will print it again and put the profile and photos online :)
