Just a little something I've been working on when I get the chance: Lynton & Barnstaple Railway coach No.16 as a 3D printable 'kit'.
Modelling in 1:35 scale, but it's easy enough to rescale to whatever (see image of 4mm, 7mm, 1:35, and 16mm scales).
Not happy with the door vents, those'll need redoing, but it's coming together slowly.
