I'm working on a new counter based on the metal gear we've used for years, with a minor modification to aid in assembly. Cost should come in on-par with the old ones.
I've contacted a number of prototyping companies to see if they would be interested in producing the metal gear assembly. Most said they would not be interested because of the highly complex nature and low volume of the pieces.
One manufacurer has expressed an interest, and I sent him my counter to evaluate. I expect an estimate to produce 300 gears sometime in mid-August. Production time will be determined then.
The counter I'm proposing will have an identical ring gear (yellow) and retainer cup (magenta) and a modified baseplate (white).
The remaining gear (blue) should be easy to obtain in low volumes. I need to look into that. My hope is to have all the pieces available in a couple months if the price is right.
