Scaling models from "our scale" to 1/18

[Evil Eye]

I'm well and truly diving down the JoyToy rabbit hole, to the point I've actually started work on designing a fully printable 1/18 oldschool Marine as a companion piece.

(Note that head and shoulder pad are someone else's STLs and are only being used for reference)

 

Anyway, to cut straight to the point, how much bigger would you need to make a 40K piece to make it 1/18 scale? I ask this not only for the purposes of upscaling STLs for customs (purely for personal use I hasten to add!) but also because I had a crackpot idea for tracking down the templates for scratchbuilding a Rhino and blowing them up to 1/18 and making a JoyToy Rhino.

 

Thanks!

So you would need to work out what scale 40k is first (32mm Firstborn is 8 foot / 2440mm), then increase the Rhino dimensions to match 1:1, then reduce those dimensions to 1/18th.

 

Loose math says 40k is 1/76th, so x4 is about right to get to 1/18th scale

Yeah I got 28mm = 6ft = 1800mm so 40k is approx 1/64th.

 

So 64/18 = 3.57 ie scale up 3.5 times, a bit less than @Grotsmasha.

 

But I would also say this is just maths. What “looks right” to the eye isn’t always mathematical, and people often complain rhinos don’t look like they could hold 10 marines. I’d mock something up in cardboard before any expensive printing.

I did a little rounding

Thanks both! 3.5X to 4X sounds about right. Certainly if as and when I do scratchbuild the Rhino, there will be some artistic license taken (as you say, 10 marines ain't fitting in the back) so maybe I need not to overthink things.
