Space Colonist HLV
The Space Colonists HLV in 1/3000 or 1/1700 scale is a Heavy Lift Vehicle that can boost several mecha to orbit at once. No weapons to speak of, but the rocket parts are all separate so you can choose what stage of ascent (or descent) you want. While you are free to rescale as you see fit, I've also included presupported versions at the aforementioned scales. Happy printing!
Notes:
1/3000 scale only comes as the capsule or the full assembly, not hollowed. At 1/3000 scale, I can fit multiple aircraft on a single plate on my original Mars 1.
1/1700 scale comes in pieces, pre hollowed with drain holes. The drain holes on the mating surfaces line up with the capsule drain/vernier holes, and pin nicely. At 1/1700 scale, I can just barely squeeze all the parts on to a single Mars build plate.
If you scale it up to 1/400 (4.25x the 1/1700 scale parts), the drain holes enlarge to be the right size to accept 5mm rare earth magnets so you can assemble or disassemble as you see fit. At 1/400 scale, I can just barely squeeze the main capsule onto my Ender 3 FDM printer.
