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.

The Space Colonists Purple Cargo Ship in 1/3000 scale is a space ship that can carry several hundred tons of cargo and supplies. No real weapons to speak of, this resupply ship stayed in service for decades. While you are free to rescale as you see fit, I've also included presupported versions at the aforementioned scale. Happy printing!

Notes:
At 1/3000 scale, it fits on my original Mars 1, but if you increase the size to 1/1700 it will require a bigger printer like a Saturn.

The Space Colonists Purple Plane in 1/3000 scale is atmospheric transport plane with that can carry several mecha at once. With two twin cannons, space for 3 mecha, and a front and back door, what more could you ask for? While you are free to rescale as you see fit, I've also included presupported versions at the aforementioned scales. Happy printing!

Notes:
At 1/3000 scale, I can fit multiple aircraft on my original Mars 1, and if you increase the size to 1/1700 it will still fit in a Mars 1, so happy printing!

I've included two versions - one with higher smoothing and face count, one with reduced. Some slicers were having trouble with the high res one, so this should help.
