Off the top of my head some things we'd need:
1. Precise dimensions of the Dev Kit.
2. Precise dimensions of Beta II (allowances made with and without battery)
3. Weight of the Dev Kit.
4. Weight of Beta II enclosure empty.
5. Weight of the Dev Kit and Beta II enclosure combined.
6. Scaled down drawing of the Dev Kit showing measurements.
7. Scaled down drawing of the Beta II showing measurements.
Anything else you can think of?
