The nickel doesn't seem to have enough momentum/weight to spin the disc and continue the path it needs like the quarter. Quarter works fine, penny and dime works fine. Nickel rolls down and hits that first disc, moves it a little and just stops. I can flick the disc and it spins forever when unhooked from the connecting lever in the back. A fun and challenging build overall, wish the nickel worked. Any tips? (edited)

@PTownBandit I'm starting to think the design might be too challenging to be easily printable. I got it all tuned up to my printer and filament and profiles and it doesn't seem to be working well for others. I apologize for the difficulty.

What I would do in your situation is make sure every disc spins freely without the sync bar. Next step would be to make the sync bar lighter. You could do that by sinking it below the print surface so the bar prints thinner. Hopefully that'll lighten the mechanism enough to allow the nickel to push around the disc.

There are other steps you could take if you were brave enough to go into the onshape project, such as increasing the angle of the incline or lowering the little pip that makes the coin bounce at the end of the incline. The permutations start to get crazy with that, though, because it can start to affect the behavior of the other coins.

@animatorgeek Thanks for the reply, I will try a lighter sync bar and see if that helps. Either way it was fun to print.

Took a few tries with a few different types of filaments, but after a bit of sanding and some PTFE lube, it works 90% of the time. Great design! p.s. the 10% of the time it doesn't work is just the penny part; no matter what I do, after the penny is sorted, the hinge stays up, causing the failure in the subsequent sorting if I manually lower it; it works a 100% of the time, so I still love the design. Thanks for sharing! (edited)

@animatorgeek Thank you for the tip. Yes, it took a little doing, but it was well worth it, I love this model! It works phenomenally well!

@ZainS_125370 that's great to hear. I had hoped more people would post their makes, but it's nice to know at least one other person got it working. (edited)
