This is a case for the new keyboard-less kindle. It uses the plywood hinge technique, found here on thingiverse. This design was laser cut. A design was etched onto the front of the case, also using the laser cutter.
This design is based upon an original design by Martin Raynesford - please see msraynsford.blogspot.com/2011/11/kindle-case.html.
Basically use the .dxf and open it with the software for your laser cutter. This design is for 3mm plywood. Ensure the power and speed settings are correct (anyone at Nottingham Hackspace, use 320 power and 7 as the speed - everyone else, please ignore that). Then set the machine going.
Give it a good sand. Apply bees wax. Remove excess bees wax and buff to a polish (cheers, Dominic).
Etch any design onto the front.
Drill two holes for a piece of elastic. Thread elastic through the holes and sew together.
You could also use magnets to keep it closed.
Problems are that nothing holds the kindle in the case - maybe use small sticky pads?
