US Coin Sorter Revision

It’s been 5yrs since I published my coin sorter. It was not perfect, but it worked. As time went on, a few flaws were found. Specifically, occasional jams and the last coin not feeding. There were a few other things that I found annoying over time. High time to review the design.
I started looking at the biggest issue of the occasional jams. I quickly spotted the design issue, and it was not anything I had thought of previously. From there I was committed to fix everything I knew of.
I ended up touching almost every part, thus the new publishing even though at first glance nothing has changed. The jamming is fixed. Last coin feed issue is fixed. Better rigidity. Better ergonomics removing the sorted coins. Crimp storage moved to the back for a cleaner appearance. More refined visual fitment of the parts.

Hardware
M3x10 BHCS Qty 2
M3x16 BHCS Qty 3
M3x20 BHCS Qty 2
M3 Washer Qty 3
M3 Nut Qty 5
M3 Nyloc Nut Qty 1

Assembly
Look at the cross-section photos. It’s basically the same as my original.
1 of the M3x10 screw is to hold the small gear onto the crank. Use a washer with this.
The other M3x10 is at the left of the sorting rail with a nut in the base.
1 M3x20 goes though the Axel. Place a washer over the large gear, then install a nut.
The other M3x20 is installed in the top of the hopper with a nut in the base.
2 of the M3x16 screws are installed in remaining spots in the hopper, Nuts for these are in pockets located in the base.
The last M3x16 is for the knob. Use a washer on the head of the screw and the Nyloc in the knob. (This should be a Left-hand thread, but I used a Nyloc instead.)

Printing
You may need supports on the Hopper. The overhang is a little less than 45deg in spots over the curve.
Supports are needed on the Sorting Rail and Crank.
Ironing is recommended on the Rotor and Rotor Tray.
Painted on Fuzzy skin on the Knob is optional but nice. No Fuzzy skin on the shaft going through the crank.

Notes
As with my original design, the gears are from Neoprenox's design that started my journey to this design.
The chamfer on the trailing edge of the rotor holes is on purpose. This prevents double feeding and jamming. 2 dimes are slightly thicker than 1 nickel. Without the chamfer, 2 dimes would jam.
Dollar coins are not supported. They will stay in the hopper and not feed. So sorted but not stacked.
