Making pumpkin boxes

Posted on October 17, 2021 by robertwilkie

The “face” is CNC’ed out and uses standard templates you can find on the web. The sides are just all the sides of a box cut up (so you make a square box). Pretty simple build. https://www.instructables.com/Box-Jack-O-Lanterns/

PVC made CNC

Posted on October 7, 2021 by robertwilkie

Its a plotter/laser engraver build. Overall pretty clever build. Reminds me of the little CNC’s made 10 years ago with iron pipe. https://www.instructables.com/P-CNC-Laser-Engraver-and-Pen-Plotter/
