TiggerBot II’s main components are all computer designed and custom manufactured.

The plastic components are designed in solidworks. They are then separated, duplicated, packed together for efficiency, and printed as a 1:1 eps. This is sent to a plastic manufacturer to be cut from acrylic.

The circuit board is designed in eagle cad and manufactured by a pcb prototype supplier.
