Every tuesday FabLab Amersfoort is open from 10:00 to 22:00 hours. We expect visitors to do something in return for using the lab. The system for that is as follows: On entry every visitor pays €50 cash. To earn those back you have to do something that is worth the same as using the Fablab has been worth to you. That can be anything: You can share your design, you can fix the lights, you can give us a tool we need, or leave (part of) your payment behind. At the end of the month we will use that money to pay the rent, do maintenance and buy new machines.
