Blank impact round for CTL

thingiverse

Human: Impact grenade for CTL platform. It detonates a blank 8mm round on impact, making a loud noise that's really fun to shoot and useful, especially in CQB games. Launcher link: https://www.thingiverse.com/thing:3345144 Update 13/01/2019 - added body with no bushing required How it works: File Head.stl is the hammer for the blank round. It must be tapered with a M4 tap, and a point screw must be used. Use a screw as light as possible since this piece is really light, it doesn't set the primer when fired with green gas. When the grenades impact, the kinetic energy of the body sets off the round. For this reason, it's essential to have a projectile body with a weight of about 30g. You will need a 30x11x8 bronze bushing to give the projectile some weight and contain the round. These are widely available and cheap since they're the same used for ultimaker or similar printers. You can try printing the Body_NoBushing.stl file if you want, it works just as well, but make sure it weighs about 25-30g https://www.aliexpress.com/item/1pcs-8mm-bearing-bushing-3d-printer-accessory-Ultimaker-copper-bush-8-mm-11-mm-30-mm/32475766859.html?spm=2114.search0104.3.15.7d9733c8duMQDL&ws_ab_test=searchweb0_0,searchweb201602_4_10065_10068_319_317_10696_10084_453_454_10083_10618_431_10304_10307_10820_10821_537_10302_536_10843_10059_10884_10887_100031_321_322_10103,searchweb201603_53,ppcSwitch_0&algo_expid=7803cb55-a181-4ba8-802d-f0790f21b2e5-2&algo_pvid=7803cb55-a181-4ba8-802d-f0790f21b2e5&transAbTest=ae803_4 How to use it: Turn the screw until it comes out of the head (1mm). This is basically a safety for transportation. Insert bronze bushing and blank round in the body. Cover head in vaseline or grease so that it doesn't fall off when pointed down, but at the same time doesn't increase friction. Safety precautions: Don't shoot too close as backfire from blank round may ignite green gas (from 2 meters on you should be fine) Don't shoot directly at people, shoot to walls to clear rooms. Don't reuse the grenades, they're disposable. Please respect the environment and use PVA, PCL or at least PLA. Don't place anything on the back of the projectile as blank round energy might propel it violently. I am not responsible for failures of your systems or injuries caused by misuse. Just be a responsible person and don't be a dick. https://youtu.be/kC4ZyRcSi9c https://youtu.be/-aEeJ9XTUrM
