Posted on February 6, 2019 by robertwilkie

Interesting build. Me…well its a nice idea but the size of most 3D printers I could just “print” the design out on a regular printer. https://www.instructables.com/id/Plotter-Using-3D-Printer/

Make your own carbon fiber tubes

Posted on January 24, 2019 by robertwilkie

I never realized how much these things cost. but apparently the ribbon for carbon fiber is pretty cheap, so the author took and arduino, some steppers, and made his own tube maker. Clever build overall. https://hackadaycom.files.wordpress.com/2019/01/carbon_feat.jpg?w=800
