I got a bunch of build plates with holographic surface texture, and I wanted to have parts that I could check quickly in case I wanted to do a specific combination of bottom surface pattern and plate texture. Global layer speed is cranked down a notch to help with adhesion on some plates. Top and bottom surface patterns are matched for checking what the pattern supposed to look like vs. what was deposited on the plate.

Parts are nominally 20 mm x 20 mm x 2 mm with 5 mm fillet around the corners and 1 mm fillet on the top surface. Hole is about 4 mm in diameter.

Edit 05/30/24: Please make sure that the Plate Type matches what the plate seller recommends for your particular plate. Also, my print profile isn't universally suitable for all the plates that are available, so some tweaking with the temperature and print speed might be needed. Please monitor the first couple of layers for proper adhesion.
