UPDATE: Now includes a narrower A1 mini version.

I saw a model similar to this one, but decided to make one from scratch*. The photo shows one I made for a friend with the dental office logo on it, but the provided model doesn't have a logo. It's just there to give you an idea. I also threw in a 2-layer rectangle the size of a business card if you don't have one on hand to test with.

I used Bambu Labs PLA filament:

• Basic White (for the tooth, Basic is a little shiny, looks good) 
• Matte Ice Blue (for the base, has a “dentist office” vibe)

*I used TinkerCAD. If you're new to 3D printing and think CAD programs look crazy difficult, check out tinkercad.com. It's basically made for children and people like me. Free and super simple. (Not a paid endorsement, just a fan)
