So they contain many approximations that don't hinder their display usages, but are not precise enough to get good mechanical properties. For example pin holes are modeled as 16-sided prisms instead of true cylinders. That's enough to cause pin insertion problems!
That explains it, thanks.
The models are quite close though and i think that if base parts could be tweaked, then the usage model can be extended to hobby printing too
Don't mind the 16-sided prism, the printer makes it quite close to a cylinder, so pin insertion is not such big of a problem. The radius of the cylinder and the inner spacing of the axle hole, however are a blocker
