A stamp in a case for embossing paper and card. The stamps are changeable with two examples included.

The top includes slots for storing the spare stamps, which also provide rigidity even when the skeinforge fill settings are low. For similar reasons the bottom includes pillars that help transmit the force evenly across the whole template area.

The design is in OpenSCAD and fully parametric including the size of the design area, the thickness of the base and templates, and the gap between the lid and the base, which should be based on the thickness of the rubber you use (see instructions below).

A rubber sheet must be attached to the inside of the lid; it can be made of thick rubber bands, neoprene or even foam rubber. I cut up one my kid's rubber wrist bands (it's for a good cause) and threaded it through the holdings slots on either side of the top.

There is very little support material required (by design), but remove any material around the hinge very carefully. Fitting the hinge parts together should be done at an angle to reduce the strain on the whole retaining hinge.

When embossing, place the case on a solid surface and press down hard with the heel of your hand. Alternatively squeeze the case in a vice or G-clamp.

The design is original except for the MakerBot 'M', which I took from one of the bottle openers.
