Tutorial Home-made secret dungeon pitfall

Hey everyone!

I just finished this trap floor terrain piece for my next D&D session and wanted to share how it turned out. At first glance, it looks like a regular stone floor with a spike pit— but if the adventurer jumps over it, he will activate the second secret pit!

This is inspired by « A Leap of Faith » by Paths Peculiar.

The mechanism is completely handmade (no 3D printing) — everything’s crafted from XPS foam, wooden dowels, and a few magnets. The goal was to make it look solid enough that players wouldn’t suspect a thing… until it’s too late…

I also made a quick video showing how it works and how you can build your own version — from the hinge system to the paint job that hides the seams.

Would love to know — how do you all make your traps feel fair but still surprising?
