Same here in SW, after all the student degree shows and similar events the summer seems to be quiet (but thats been the same pattern for years) - however not usually this quiet.
I’ve had a few customers that couldn’t find us on the 3D Hubs search list since the changes and find that the search order is now bizarre… Even if I search for a hub in my area the recommendation don’t seem to be based on the factors 3D hubs says (response time, cost, reviews etc).
On the up side of the summer we are getting more work from yatch designers and similar - might be worth looking at local businesses that have a more ‘summer’ trade and offer up your services.
