$75*30 = $2250!
To bring this discussion back on topic, I think there is definitely room to create a modular dummy axle system to reduce cost and material waste, maybe not for the existing users, but for the future.
Maybe that needs a 1in dummy sleeve, or maybe it can be done with the current standard, but I think the community and toolmakers need to see the potential before they can buy-in.
This is another advantage of the open-fixture project, you can branch off designs and sub-assemblies however you want. If someone wants to design a 28.9999 DUB standard dummy holder to show the world what we are missing, no one can stop you!
