This is a double-sided version of my Fast Print Hexmaille Fabric. It doesn't print quite as fast, and it's not quite as flexible, but it's smooth and shiny on both sides!

This was originally inspired by TurboDork's NASA Fabric, which used identical interlocking pieces. This design, however, uses hexagonal tiles and separate interlocking rings, which allows the fabric to be a mere 3.2mm thick. The rings are printed right on top of the tiles - kind of like removable supports. They have minimal contact with the tiles below, so they are very easy to break free. I've included an 8x10 grid of tiles as well as a single tile and ring for inspection.

Printing
The layer height needs to be exactly 0.2mm for the clearances to work out correctly. If using PrusaSlicer, you should set the line width for perimeters to 0.45mm for most efficient printing. I used PLA with the 0.2mm layer thickness “speed” profile, but I was able to bump up the all the perimeter speeds 60mm/s. 

Post Printing
The process of loosening up the fabric is very tactilly satisfying, kind of like popping bubble wrap. To break everything free, you just pinch adjacent tiles with each hand and give them a little wiggle relative to each other. You'll hear little snapping noises as the rings break free. But like popping the last bubble in your bubble wrap, finding each and every connection to break is a little challenging.
