Coffee Saver is a project to create a reusable and versatile cap for an open bag of coffee granules, which can be produced on a 3D Printer.
The main CAD software used for this project is OpenSCAD with additional functionality provided by Dan Kirshner's OpenSCAD Threading Library and PGreenland's Text Library.
Version 3 allows the cap to be placed over the open bag and clamped in place by the two external clips.
This Thing has been tested on a Makerbot Replicator 2X.
