I made this keychain impact mini grenade for the updated version of the v1. you can see assembly from the pictures. Hardware: -m4 x 12mm screw -m4 nut -m3 x 23mm screw -m3 nut -a spring: right now I have a spring with dimensions 8mm x 33mm with wire diameter 1mm -a cotter pin -keyring -10mm piece of a lighter spring (These are what I used most recently, but I recommend you to test different springs and screw lengths) Filaments: -For the newer (green) version -spoon: light gray pla+ -Body: Bambulab olive green abs -Other parts: Bambulab black pla basic What I recommend: -Does not really matter too much - Pla+ is the best for this i believe Let me know if there are problems with it. If you like add a rating. Thanks!
