Laing DDC Pump

Little thx to the community for the files I have allready downloaded from grabcad, saving me a lot of time and boosting my crativity. Just the outer shell from the laing DDC pump for integreating in some PC watercool projects. I draw this file in autocad with the laing PDF instruction file, with some images and videos from the web as my drawing sources. Gues the precsition roundabout +- 0.4 mm.
