Message:the other in Map & Dice Playing Cards by Inked Adventures and I have. I have Inked Adventures Dungeon Cut Ups for the mini dungeon. However they are just a bit to big. 4 or 5mm scale.
The miniatures are from Microworld Games the only company making 3mm Scale
So with a Jeweler's Saw I carefully cut them into individual minis. Then carefully file them into proper looking shape. Next I mount them on 4mm x 1mm disc magnets.
Yours,
