These will probably be released at the end of this month I think, just have some tweaking left to do. I'd estimate that all the files take approx 30-40 hours in total to print with 0.4mm nozzle, 0.25mm layer height and 60mm/s main print speed on a standard 3D-printer with a 20x20cm bed.

You can visit my website and leave your email at the very bottom, and you'll get a reminder when I release something or start selling the kits/electronics.
