Already have a 3D printer and want to print out our grenades for your costume? This is the most recent version of our now famous Death Trooper grenades. This file has been printed thousands of times and is fully tested. A lot of work has gone into making them not only print well but also work well. The two halves easily screw together and there is a place to put in a small "balloon blinking LED" with a cap (see photos, not included) Not that this is a much more accurate and better working version of the file I uploaded two years ago on Thingiverse which many people have printed out. The threads work better and the whole design prints way better. Please note that the license is for personal use only. Commercial sales of these is prohibited. If you would like ones we have already printed, look in our store.
