Foreign coin storage tube

thingiverse

I use this device to stack and store coins of various sizes, allowing me to keep my inherited coin collection organized without taking up too much space in my cupboard. I don't want to sell it, but I don't want it to waste valuable space either. To adapt this to the coins you want to store, you must use OpenSCAD. The key is to modify the `coin_sizes` vector at the beginning of the code. Simply input a pair of values for each coin size you want to store, including diameter and height of the coin stack. Follow the example provided, but substitute your own coin sizes and numbers. You can use as many or as few value pairs as needed. I personally prefer to stack the coins from smallest to largest, with the largest on top. This makes it easier to retrieve them later. Alternatively, you could place small coins on top and seal them in during printing for a more secure storage solution. The lid of the device can be secured using a bit of Tesa or other stick tape without any issues. I designed this device specifically for storing foreign currency coins, as I usually have enough of one size to make cylindrical rolls instead. If you're looking for a tool to help with these paper rolls, I highly recommend checking out this roll helper on Thingiverse.
