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.
This product is priced at $0.99
