Your futuristic war machines shouldn't be slogging through swamps and deserts to find their foes. Take it to the streets with the Smelly Old Gamer's line of buildings.
My own original work designed to be compatible with BattleTech and other 6mm Games. In BattleTech map scale, this is 1 Level, 4 hex residential building.
Files are provided to either print as a single structure or with detachable chimneys so that units can perch on top.
Print BulkFactory2 v14.stl if you just want the single file print.
Print ONE of BulkFactory2_Base v14.stl and TWO of BulkFactory2_Chimney v14.stl if you want removable chimneys. Note, because there is less travel time for the tool head, this approach prints faster on an FDM printer if you print all files separately.
This is a Work in Progress, but I successfully have printed this on a mini+.
For all of my buildings, I recommend 1.2mm wall thickness. I design them to be “acceptable” at .2mm layer height for FDM printers.
No supports needed if you've got your settings dialed in, but I always use a brim.
