Euro drainer / sorter / sieve

thingiverse

We have a dish made of clay by my son at school which we use as a coin container and dispenser. We drop whatever we have when coming home or pick low amounts for the bakery or other small payments. The issue was that all the small coins like 10 and 20 cents remain and fill the dish while the bigger coins cannot be found too easy. This sieve is sorting the coins automatically in a usefull way: Remaining coins: 50cent, 1 and 2Euro (for daily use) Dropped coins: 20, 10, 5, 2 and 1cent (for the bank) Function: DROP a few coins from pocket or bag into the dish. Usual no further action is needed. ( Most smaller coins will find there way directly into a hole. Others will drop later once picking up few Euros or slightly moveing the sieve. ) PICK up larger coins for e.g. ice cream ... ( Repeat actions whenever needed. Pour small coins into a bigger container from time to time or and bring them to the bank. ) Tribute to me ;) : It surprised myself how good it works (small coins are gone like nothing, and Euros do not jam in holes at all) using the following parameters: HOLES: The size of the holes are 23 mm diameter. 20 cent (22.25 mm) and smaller coins will fall through while 1 Euro (23.25 mm) and 2 Euro and 50 Cents will remain on top for usage. DISTANCE: I thought a distance between the wholes would be ok with 1.2mm (3 lines of filament with 0.4mm nozzle) THICKNESS: The thickness is 1.5 mm which is ok for this size but I would use 2 or 2.2mm next time. RIM: First I used the 4 mm rim to hold the coins in sieve (picture). Later I used it upside down so dropped coins will release the holes right away. (coins getting blocked between dish and sieve is not an issue) Have fun creating similar thing for your own needs :) ...
