Christ, I've been working on this for the better part of a year 😶😶😶 I originally started this project to use in my Adepticon 2020 game, Upheaval on Tanjarax IV, which never happened. It's finally finished.
It's kind of a 3 way mashup of Wyloch's sector mechanicus walkways, the box making techniques of Sage Reynolds, and the hand-drawn style of Warhammer Townscape.
Most of the following pictures were taken before I applied the final spot colors, and they're far from comprehensive. I can take some better ones if there's any interest at all but otherwise I couldn't be arsed.
The boxes were constructed of heavy duty chipboard—not the grafix brand that Wyloch favors (since I despise amazon and refuse to order my supplies from there) but the Blick brand which you can order by the sheet for peanuts. I went with the 30-ply, which is very heavy duty indeed, but I think you could probably get by with the 14 ply and save your utility knife arm some strain.
I also made some extra support pillars and stairs, but because no design is ever perfect, they don't fit in the main box. Instead, I have a painted notecard box from the thrift store that I'm going to give the same treatment. It will also serve as the maintenance bay for one of the large vehicle objectives in the Tanjarax game, someday.
Lemme know what you think by delicately nesting your comment into the box provided below.
