Print-in-Place Hex Pixel Panel

This pixel panel consists of pivoting 2-color tiles that can be flipped to create pixel art. The unlike my first pixel panel, these hexagonal tiles lend themselves to more organic designs. I've included a stylus for poking at the tiny tiles to flip them, and also a stand/frame to display your panel.

The pixels are 5mm across and the whole panel is only 2mm thick. By executing a filament color change halfway through, each pixel ends up with contrasting colors on each side.

This is a challenging print in that the clearances are tight and the little pivot pins are tiny. This really needs to be printed on a printer with mesh bed leveling, well tuned pressure advance, and a direct drive extruder. (Bowden extruders can struggle with tiny details.) I've included a small test patch that you should print first to make sure your tiles will pivot before printing the whole enchilada, 

Print in PLA with 0.2mm layers and a 0.4mm nozzle or smaller. Change to a contrasting filament mid-print after 5 layers (1mm). Once printed, use the stylus or other small probe to poke at each pixel tile on one side to break it free and make it rotate. Note that adjacent tiles rotate on different axes. If you hold the panel up to the light, you'll be able to see which way the axle runs for each pixel. Once they are initially broken free, just poking each one in any corner will cause it to flip, so you don't have to worry about which pixel pivots which way.
