just a simple template for a vault dropped generator (don't forget to destroy the thatch ceiling by hand/rifle/whatever)
the template got the 16x16 foundation template, the cage, a vault drop layer and the railing roof - the cage should auto build without problems - the vault drop layer need a flipped frame between cellular and thatch layer to auto build (like on the screenshot) - the roof also needs some steps until auto build - you need a 7 wall high double door frame for the best place of the roof (if you flip the frame you are able to choose the perfect direction of the roof) like on the screenshot you need to place 3 thin metal beam to get it fully auto build (don't forget to fill out the sides with double doorframes - it is easier to copy&paste it without many snaps) - i also added another version of the railing roof but this one is optionally i hope you like the design. its not perfect but just change something if you want to improve it! :)
