Where are my 3d-printing customers? 19 April 2017

I've been selling 3d prints via 3dhubs and directly for several months now. Where are my users?

Since I send most of them out by post, and deliver the exceptions in person, this is easy to work out, especially given the CodePoint Open postcode data set freely available from the Ordnance Survey.

Red crosshairs are 3dhubs customers; blue ones have come directly to me, mostly for boardgame bits. 3dhubs does favour hubs closer to the customer, being based originally on the pickup rather than postage model; I think that may be why I'm getting proportionally more orders per local population from London than from the West Midlands or Manchester. (About one order per million people from around the M25, compared with about one per 2-3 million elsewhere.)

I haven't shipped any 3dhubs orders outside the UK yet (I've only just added the option), but I have sent some of my custom boardgame bits:
