If you want to have a model of a starship that is a meter long that is an exact replica inside and outside of a 1000-meter long starship, it is best to have micro-machines constructing it in zero gravity or in a space dock inside the chamber.  You can even have a crew of 2000 micro-machines.  If you want it to be powered like a real starship, you will need a miniature hyperlight reactor which will make the model cost about $10 million more.  An injection reactor will cost only $500,000 more.  A powered starship will be able to fly at hyperlight speed and be able to use its weapons.  But with a basic non-powered model costing only $600 if you already have the construction chamber and micro-machines, most people go for the less expensive model. 

You can even buy replicas of the furniture in the Functional Art Gallery and GSLP systems so that you can send a powered projectile to the moon, if you want.  By the time outsiders return to the moon, whenver that is, they may find a bunch of projectiles littering the surface of the moon.  If they know about the Harvenstall Art Museum’s gift shop of the science museum’s gift shop that sells the same system, they will know the things are from Newgate.  With an art gallery gift shop unlike any other art gallery gift shop in this dimension, it will be pretty easy guessing where the stuff came from. 

Spend a few minutes to pick up what you have made for you in the galleries.  All that is made is transported to the shop’s back room.  You don’t need a claim ticket because every person that buys something in a gallery is scanned and his identity is programmed into the gift shop’s visitors computer.  Some lucky customers are given daily coupons so that they can purchase things for less.  And often one visitor that enters the museum is given a special card when they go to the gift shop which allows them to go to the museum at any time for a year free of charge and buy items for between 10 to 50% off.  Not bad when the admission price is less than an outsider would pay to see a movie and have popcorn and a drink.  And in my opinion, it’s more interesting to go to the museum than watch a movie no matter how entertaining it is.
