// This renders engineering templates for my sous vide cooker.
// All shapes print out at their designated sizes, so making
// engineering diagrams is easy. These templates were printed and
// rubber-cemented onto a steel project box and cut out with a drill
// and a nibble-notch tool, which are actually the other handyman's secret
// weapons.
//
// Now if Frink could only control a computerized milling machine.
// Which, I guess, I'd have to have it build first.
