Pneumatic Pyramid

“Create hole for valve at crosshair. Be sure to only puncture one side of the pouch.

Seal along the solid lines to create pyramid structure. Use 1.25 in. cutout (bottom left) as a shield such that only a space equal in length to each inner line is exposed to the heat press. It can be taped directly onto the heat press with painters tape.

The pyramid can be created from scratch using this guide. This example has 6 inch sides, and has an inner triangle with 3 inch sides. The diagram below details the measurements for inner parts of the model. These can be treated as rough measurements, as different configurations will create different folds.”
