This is a simple wall tile I created in Blender, it is far from perfect but i needed something simple to cover up a messed up wall.

One tile requires only 32 grams of filament so you can print a lot of them from one spool.

I included a blank tile for you to put whatever pattern, logo or text you want on them.

I print them with 0.28 layer height, 10% grid infill, concentric top/bottom all at 60mm/s.

Update: Fixed small "glitch" in the hex tile Added half tile - Slicer will complain about the model not being manifold, but it will slice it. I will try to fix this later

Update 2: Fixed the non-manifold problem
