So what do you consider to be the best 005, or 01 to use with an EggBot Pro? I’m a bit of a perfectionist. Use to do CNC programming for WDW, and now do Computer 3D modeling, and rendering, ( I have attached a sample of my work ). I must say this EggBot Pro is beautifully thought out, and built. Cosmetically it looks great, and has a very solid build. Almost resembles a miniature CNC lathe. Are there any ball point type pens that work well?
