My hobby in retirement is now 3D printing. I have a Printrbot Simple, a Mini Kossel and just finished assembly of 3DR Simple as designed by JohnSL. My plan is to build "Sketchy" as designed by jarkman (aka Richard Sewell). Then share this with schools and my granddaughters as a science fair project. Maybe too complex for young kids. Probably will target high school students.
The parts are described here:
Working on documentation of parts, sources and prices.
Looking at the above website lead me to the TRC forum.
I will start a new thread with this info.
