Any chance of openbuilds making hardware for m6 fasteners for the wheels? Specifically eccentrics and spacers? Seems like it would be a good upgrade as the m6 should be a good bit stiffer than the m5 and there are bearings that will fit in the larger wheels with a 6mm ID.
Not surprised to see that and not surprised to see that from Misumi it's almost 3x the cost of the Open Builds m5 version. Affordable aluminum spacers are a bit harder to find from my experience. I've looked at that site before but sizes are limited, ie no 1mm precision or 3mm and 6mm
