Airsoft spring grenade
cults3d
Its a simple 3d printable AEG SPRING grenade. A cheap multiuse alternative for gass grenades For printing pistons i suggest 100% infill And i suggest lubricating the piston and the inside of the housing for smooth operation if 3d print is not smooth enough, i use silicone spray same as for gbb pistols... I have also added housing with longer screw bezzles that will take 3,5x40 wood screws so it can mannage stronger springs. Due to som longer springs tend to twist i have made a spring guided version of the piston they are compatible with all housings and they use a 100mm m5 screw with chamfered tip and one m5 nut. (i have not fully tested it yet but first tests worked fine, i will develop this even further in the future) https://www.youtube.com/shorts/4rDgNJKlneY
