Coin Storage Tubes - Dimes - Quarters

thingiverse

These are simple coin storage tubes I designed in Tinker Cad to hold "junk" or constitutional" (pre-1965 90% silver) coins, but there is no reason they shouldn't work for regular fiat currency either. The design is intentionally thin, allowing you to squeeze the tube to pick up small stacks of coins, adding them to the tube. The dime tube should be sized for 50 coins ($5 face), and the quarter tube should hold 40 coins ($10 face). Older coins tend to wear and be a bit thinner, so you may need to elongate the tubes just a bit if you're dealing with newer, full thickness coins... but it should be pretty close and the cap should hold well regardless as it is. I would suggest printing solid, all walls, no infill. I find that turning on ironing makes a nice interior surface, and helps everything hold well together.
