Grow-tall savings tower

Save coins in a money box that grows a level taller as each one fills

Saving is easier when you can see it grow. Coins drop through the slot in the top cap and pile up from the bottom, visible through the clear walls. When the coins reach the top of a level, add another one underneath the cap: the tower literally gets taller as the savings grow. Write the goal on the cap with a marker, and lift the levels apart to count up.

How to print it

Print in clear or translucent PETG so the coins show. Each level prints separately; they stack on rims and lift off to empty.

Prints as shown on its floor, no supports. Stacked parts are fused into one print.

Filament: at most about 191 g of PLA printed solid (roughly $3.83 at $20 per kg); normal infill uses less.

To get the files, open it in the generator and choose File › Download STL (one file per part) or Download 3MF (every part on one plate).
