I have downloaded the OpenLock Tessellation templates and have designed a seperate floor texture file that can be glued on top to create a completed floor tile. Now I want to combine the two STL files into one file. What is the best way to do this and produce a clean distortion free file for printing. I have tried both Meshmixer and 360 but both seem rather cumbersome to do a simple join.
Thanks, I am new to the 3D printing thing so forgive me if I have overlooked something obvious.
