Do some 3D Modelling

Design a milled aluminum case to fit our circuit board. This simple case will be based on an existing case we like a lot, with some modifications (size, hole size and location) to fit our circuit board. Exact measurements and specifications will be provided, a complete redesign is not needed. Previous experience designing a successfully milled aluminum case _is required_. *5x5 inner PCB *4 holes for light pipes (to be chosen) *2 slots: main header, programming header *1 slot: USB connector
