You can get 6mm shaft from McMaster and a number of other sources.

Of course this drawing of the hub shows the bore to be 5.95mm or .234"


I wonder if you could take the motor hubs and drill them out to 1/4" That would give you a bunch of options. The little nub that centers it inside the gear/wheel/etc. is 7.97mm or .313" so there would be material left to center the hub and use them as normal. D profile shaft 1/4" diameter at McMaster is ~$9 for a foot long piece.

Then what are you going to use as bearings and how are you going to provide support for .250" shafts passing through or across the Tetrix structural elements?

Shaft bearings must be supported. The 3/16" bronze flanged sleve bearings that insert directly into the Tetrix components make assembly so simple.
Any new shaft schemes that are not compatible with them are going to add a lot of work.
