Back in 2010 my life had been nothing but pipe drafting. So, I had this crazy idea bouncing about my head. Us weasels would make good plug valves; or least, decent pipe cleaners.
I did this using the title block format. The dimensions and symbols aren't 'completely' accurate for this isometric drawing. I just really added them for background noise, so to speak. This was a fun practice on a normal weasel, and another excuse to learn how to draw faces and toes better.
