Compact Coin Sorter

thingiverse

I was blown away by Eugene's Coin Sorters and the tremendous progress he has made on this item. A couple of improvements caught my attention, and I thought I could take them to the next level. The first one involved modifying the tubes by extending the main body and coin tubes slightly so that I could adjust each tube to match what standard coin rolls hold (50 pennies, 40 nickels, etc.). I was only able to verify the height of the quarters and pennies since I didn't have enough dimes or nickels. Please let me know if either of them need adjustment to be flush and I can edit the files - the math should be spot on. I then added a full round top to the main body and combined the pin sticking up on top as one piece. This was a challenge, as 6-8 hours later I had a fantastic looking part except for the pin on top which was all misshaped. The cross-section of the layers being so small that there wasn't enough time for the part to cool down. I also had some concerns about the holding power of the hopper and the layers running horizontally, as it might be prone to snapping off the pin. Not wanting to rebuild the whole part if this were to happen, I revised the design so that the pin is a separate piece (along with an additional shim) that you insert through a slot in the quarter opening. First insert the pin and slide upward. Then insert the shim in the remaining void. Being trapped from below, it will withstand the pull force of taking the hopper off each time without requiring any glue or screws. I have since found a new base by Dralion that is similar to my first attempt and looks very nice. He combined the pin which gave me trouble, and I assume his part will be too short for my tubes.
