Archimede's Coin boats

thingiverse

We can forecast whether an object will float or sink by knowing its weight and volume, thanks to Archimedes' principle. To test this concept, I created two calculators to verify it using simple geometric shapes: a cylinder and a square boat. In the advanced version, you can choose the type and number of coins, their arrangement in square rows, and the gap between them. The formulas will then calculate the dimensions of the boat to print and determine how much diving is required. There's also a simplified version where you have to enter all the data manually, but it still calculates the amount of diving needed. I printed both boats using PLA with a 0.4mm nozzle and a wall thickness of two.
