US Coin Sorting Machine (American Coin Sorter)

New and improve Version 2 now available, please be sure to download the version 2 profile!

I have adapted McFly's model to use American coins instead of Euros. Of course, there are a lot more European coins (8) than American coins (4), so I've basically doubled up on each denomination. As an added benefit to this doubling up, should a coin not fall into the first slot (something that I have not seen happen yet), then it should fall into the second slot.

Assembly is fairly intuitive, just look at the picture and you'll figure it out. I've made minor adjustments to the functional parts so that they are easier to put in place.

You will also notice that there are slits in the tubes that hold the coins, each bar going across the slits is the location of every 10th coin, so not only does this machine sort, but it also helps you count! To remove the coins you will have to remove the hopper.

Version 2 improvement:

I didn't like how it difficult it was to remove the hopper to get out the coins once sorted, so I came up up with a simpler solution to removing the tubes that doesn't require disassembly.  Now, the base of the model is printed in two parts and are threaded, so you simply need to unscrew the bottom of the base to get the tubes out.  Then when you are ready, insert the tubes back into the top part and screw back on the bottom part.  This is a huge quality of life improvement over the original model!

IMPORTANT: Only turn the crank counter-clockwise! This will allow the coins to fall into the correct slot. If you turn the crank clockwise, everything will fall into the quarter tube. Also, keep in mind that the tubes need to be arranged from smallest to largest in a counter-clockwise fashion, so dimes, pennies, nickels, and last quarter.

I've included two files, one for the A1 Mini (4 plates), and one for the A1 / P1 / X1 (3 plates). I opted for red, white, and blue so it looks a bit like an American flag, but of course you can make it any color you want. You can also move individual parts around onto different plates if you want to use more than 3 colors.

I hope you enjoy this, my kids are pretty excited about it!
