A pizza 1/20 th of a planet to make universe matrixe at 600/min with use of DF factory, the BP does its own : -photon, -spray, -warper -power
( you may need a slight add of power at first ) with shield and BaB to help the build, better to use on a PITS
The BP allow you to ship to it : Spray and photon
Belt are already in place and branded if you want to make the following thing off world : -Graphene -Nanotube -Particle container
(for the last 2 it can be a good idea for a better output and less vessel flying as nanotube take 6 time less space than moving spiniform, and particile container take 15 time less space than moving Unipolar )
