Be Excellent to Each Other is the single most important guiding principle of Twin Cities Maker.

Essentially, it means that while your interactions with members and resources (space, tools, materials, etc.) should certainly be fun and valuable to you, you'll get a lot more out of them if you put more in.

Some examples:

1. Leave the space cleaner than you found it. It sucks when you want to start a project but you have to clean for an hour first. If everyone cleans as they work, it's a better space for everyone.
2. Know how to use tools safely and properly. Using a tool wrong can damage the tool, wear it out faster, or put other members at risk.
3. Share your skills. Teach classes, give advice when asked, share your jigs and techniques, etc.
4. Enough with the CRT's already! No one wants them, don't bring them in unless they're for a project you're doing.
5. Learn from others. Everyone here, no matter how “green”, probably can teach you something. Listen to them, support them, and learn from them!
6. Replace consumables you use. Use a fair bit of wood glue? Buy a new bottle. Use some sandpaper? Leave some paper towel behind for others to use. Replenish stuff that's low when you see it.
