I like the idea of TUG bottle openers. How about key chains or luggage tags?
My spouse runs the laser department at our local maker space. They also have a CNC machine. It's a nonprofit model, and there's 3 D printing, a pottery department, full wood and metal shops, a textiles department, screenprinting, etc. It's like a gym membership---access to expensive, fancy equipment 24/7 whenever you want, and you don't have to make the upfront purchase investment yourself (plus, access to experts to help you use it correctly, and maintain it.) It's a *whole* thing....
