***TLDNR: There are tons of awesome 3D files and designs for Mansions of Madness, my respect for all those who have designed for the game.
Personally, I found the doors, and the secret passages, way too tiny in scale, tiny in comparison to the cardboard tiles they were replacing, and tiny in comparison to the character minis, that would not be able to fit through the doors.
I also wanted Secret Passages, that resembled the art on the tokens better, of an open secret door. The only ones I had found, to me just looked like a piece of furniture, unless you looked at the back. I remixed them, and the results work better for what I wanted for the tokens, and for a game like this, I share what I design, and what I remix.

I recently dusted off my copy of Mansions of Madness, and realized, in painting the minis, and finding the 3D printed upgrades I had printed for the game, were done when I first started 3D printing.

They were pretty bad. I didn't have a resin printer, my FDM settings were bad.
In reprinting better-quality versions, I found that in my opinion, the tokens I had found here for the doors, and the secret passages, were under scaled, in comparison to the other tokens, and in comparison, to the original cardstock tokens they were replacing, and in comparison, to the character minis.

I also felt that the secret passage tokens, just looked like decorative furniture, unless you looked at the back, and saw the concealed door.
Also the art on the Secret Passage token, is of an open secret passage, and I wanted one that was more in line with the art, and I am quite pleased with how I remixed it.

All of them printed without supports on my resin printer, though supports would improve the quality, I am sure.
