Marble Machine Remixed Winder Handle

thingiverse

I thought this marble machine was a really good design. I printed it in a matte finish PLA, and really liked it. However, I wasn't thrilled about the original winder, with the depression for your finger. So I decided to try to come up with a slightly different approach for the winder. I came up with this winder handle that spins in place, and makes the turning motion a little bit smoother. I hope you enjoy it. A couple notes about the original design: Instead of printing my own "marbles", which didn't seem to fit on, or roll on the tracks very well, I bought some 7mm stainless steel ball bearings on Amazon. They roll very well. The only trick is they pick up a little extra momentum, and often miss the target, when they are supposed to drop in the small funnel. I will try some 6mm BB's and see if they work any better.
