I’m perfectly happy to share the wheel and frame STL files if people want.
Being realistic, it’s only the centre axle that needs retaining due to the gear – its worth replacing the outer axles with 2mm silver steel 21.5mm and drive the axle all the way through the front and back wheels for maximum effect. Similarly, if one has access to a Lathe, its very easy to grip the extended muff if a collet to skim the tread and face, and run a 1.8mm drill through to optimise the accuracy. The prints are pretty good, but will never be as good as one that’s been trued up on the lathe.
It has been very worth while keeping rods, crankpins etc….!
