Simple Dungeon Tiles with walls

I have been in search of a super simple, easy to print and modular dungeon tile. so, I designed this one. more styles and textures are coming soon. this is basically the "MVP" in theory it should work with 8mmx2mm round rare earth magnets. This is still very much a work in progress and i expect that i will need to refine it before adding different surface textures.
v1 holes too small unusable with standard sized magnets
v2 hole size corrected. thickened to 15mm total thickness and made 2 sided for more utility on the table
v2.3 added feet for bed adhesion
v3 textured on both sides, "feet" added to corners to promote bed adhesion. "Wood" on bottom, "Stone" on top
V4 textured on both sides, deep texture, added bed adhesion on corners and indicators to tell you what way to install the magnets.

Dungeon walls:
v1 Blank, for you to paint, remodel, or whatever
v2 stone textured no supports, great for resin printing.
v2.1 stone textured, added feet for fdm printing .2mm layer heights, 4 walls, no infill.
