Integrate social media into hub account
As a printer on 3D Hubs, I find it time consuming to post images of my prints to social media and then to 3D Hubs. My pictures on my hub are often out of date because it takes a large amount of effort to add pictures, caption them appropriately and do this continuously with social media. I would propose that 3D Hubs would provide some kind of integration that allows hub printers to connect to their social media accounts where customers can see the latest prints on a printer's social media.
The downside to this 3dhubs does not want the customer to find you and order from them bypassing 3dhubs. That is why we are not allowed to put our website or personal contact info on our profile page.
