Vacuum Clamp

thingiverse

This is a (mostly) 3d printed vacuum clamp for workholding. It is designed to be used with workpieces that may not form a perfect seal in all sections; the sealing surface on the clamp is divided into cells that each have limited air flow so the whole vacuum isn't lost if some of the cells aren't sealed.

I highly recommend editing these and compiling your own customized STL instead of using the STL I built to my own specifications. When rendering, OpenSCAD will output several pieces of information calculated from the settings. These can be important for making the gasket and redrilling the holes.
