Evidently, earning money was nevertheless more important than a nice open atmosphere. Now it is becoming a closed club again, which it may still have to have its name.I can not imagine that it is this way it is still profitable to offer your services there. As a tinker, you can get away with a few euros per hour, but if you suddenly have to keep a full-fledged administration, give up VAT (and pay it), and then also 12.5!% To 3Dhubs, then you will euro soon only about half for material, electricity, time and so on.
When I see what the prices were already doing then, only the bigger players remain, I think.
I had 5 printers, which at times were all printing at the same time. And then it was attractive to put your hobby and time into it. Anyway, with 5 home-made printers, you are well over 5000 euros further before you have printers, and a number of colors of material / spare parts and so on. Let alone if you want to put down “brand” printers.
