I have recently rediscovered my love of Advanced Heroquest and I'm attempting to recreate my own version of the game pieces with my 3D Printer.

This is a wall section piece that fits with the flooring tiles linked below:

The above link also provides a .stl file for the pegs I use to lock the pieces together. I have also included the wall design without the OpenLock bases for use with other tabletop set-ups.

The original game didn't incorporate walls, but I use them to show which parts of a junction square are blocked/open for exploration.

If you are interested in Advanced Heroquest gaming, whether re-discovering or a new-comer, I would advise checking out;
