Currently the medium-sized hubs are just rescaled versions of the large hubs.

This of course reduces the amount resources used in-game as well as less work, but makes for some oddities:

• hand-holds are too small
• ports are too small (and hence Cpt.Kipard made these unpassable in CLS even though equivalent-sized stock parts are passable)

We could re-use the models and just use different textures if we remove the hand-holds
