This is an ulti-bot that you can print. With the file attached you can make an autoprint (if you run it in windows). It is designed so you can shove it over a Christmas light in your tree. It has a 10mm hole, so scale it accordingly until it fits over the lights you have in your tree! Note: The autoprint works for the Ultimaker Original only at this point.Instructions:-Unzip the folder.-Open the script.-Enter the amount of robots you want to print.-Autoprint is being generated.-Copy and paste the file on your SD card.-Use some 'used/old' tape, or wear it down with a bit of sandpaper, you don't want the robot to stick too well to your tape, or your printhead won't be able to push it off.-Start autoprint. Let the light shine in your house :)
