From New Frontier Games
STL (3D Model) – $0.99 USD
This ship is modeled on the silhouette of the agriculture ship from the Star Frontiers: Knight Hawks rules. It is hull size 10 in that game.
The ship is modeled at 1:3000th scale, and as such stands 94mm tall. The domes are 56mm wide across the largest dimension. Here is a printed version of the ship next to the Sathar Destroyer and CDCSS Nightwind for scale:
This model has only been tested on an SLA printer, but should work on an FDM printer as well.
