A simple filament sample in keyring size. There is a chip for the following filaments: PLA, PLA+, PETG, TPU, ASA, ABS, and NYLON. I added a blank, in case you want to add some text yourself in the slicer, or just write on it with a marker, or label it with a label printer. 

printer with 0.4mm nozzle, at 0.2mm layer height. 4 Top and Bottom shell layers, 40% Adaptive Cubic infill pattern - it looks better, so the chip gets a more solid look, and only 1 minute extra to the print time.

Happy printing
