This is the official M84 Stun/Flashbang style for the ThunderStrike V2, the successor to the original ThunderStrike Airsoft Grenade. It is impact-activated, meaning that it detonates upon impact on almost any surface (with enough force). Powered by a re-usable and unique "rotating catch" system and a cut-down airsoft sniper spring, it packs enough power to set off the large "Bang-Snap" fireworks at the base, creating a loud bang. This system improves upon the original ThunderStrike, making it more reliable, easier to print, easier to assemble, and much more compact.
If you already have a fuze mechanism, here's the Outer Body/Spoon kit: https://cults3d.sitegames.net/:2666776
Additional Hardware Needed:
(Hardware Kits Available)
1x M4x55mm Bolt
1x Cut-down sniper spring (VSR-10, L96, etc.) 30mm in length.
Exact dimensions of the spring are 1.3x10x30mm.
1x 6x20mm small compression spring (For spoon to fly off)
The best wire diameter for this spring is 0.6mm. So the exact dimensions are 0.6x6x20mm.
1x Grenade Safety Pin, at least 25mm [1 inch] long (cotter pin with keychain ring works)
Sandpaper (optional, but recommended)
Regular glue and/or Super Glue (optional, but recommended)

Assembly instructions/guide:
(Assembly guide coming soon)
Step 1: Remove all s and clean up the parts, just like for any other print. Slightly sanding some parts such as the main threads is recommended.
Step 2: Thread the M4x50mm bolt through the Rotating Catch, all the way to the end. The bolt will create a thread in the plastic itself. Make sure it stays as centered as possible when screwing it in. We would advise adding a small amount of semi-strong glue (Generic glue, School Glue, Elmer's Glue, etc.) to the end of the bolt where it screws onto the Rotating Catch to the lock it in place, since it will be rotating.
Step 3: Drop the bolt with the rotating catch into the opening of the Mechanism Body. Place the cut-down sniper spring into the bottom slot of the Mechanism Body, recommended the flat side of the spring (if using either of the ends or manually flattening one side) to be in that slot. While holding everything in place, screw on the Detonator to the bolt. It should once again create the threads for a tight fit. Tighten it until the bottom of the bolt is flush with the bottom of the Detonator.
Step 4: Place the small spring into the hole on top. It is recommended to glue it down to prevent losing the spring. Super Glue would work, but might leave residue, so any regular glue is fine. Test everything and make sure it works.
To prime/cock the mechanism: Push the Detonator up all the way and rotate counter-clockwise until the rotating catch hits the walls behind the two stationary ledges (the ledges that it holds on to). After cocking/priming the mechanism, place the safety spoon on top by aligning the small spring to the slot on the spoon and carefully pushing it down. Then hook the front end of the spoon into the cut-out on the Mechanism Body. Make sure when putting on the spoon that it doesn't touch the Rotating Catch too much, otherwise it could set it off. It is designed have as little clearance as possible with the Rotating Catch to prevent it from firing, hence being a "safety" spoon.
To load Bang Snaps (Mega Snaps) into the base: Identify the indicators on the bottom of the Outer Body (the four rectangular slits) and place two Bang Snaps parallel to the indicators. To do this, drop them in top-down from the opening and push them in to be snug. It is best to use a long tool (like a screwdriver, etc.) to help guide the snaps in place.
To use the grenade: Screw the primed and safe mechanism onto the outer body loaded with Bang Snaps. When ready to use, pull the pin (just like any grenade) and throw with decent force. It will detonate on practically any surface if thrown with enough energy. On hard surfaces like concrete and compact/dry dirt it will almost always go off. Medium-hardness surfaces like moist dirt or gravel will also most likely detonate it. Soft surfaces such as wet dirt, mud, thick grass, and loose leaves might give some issues, but if thrown with enough force it should still go off. Plus, throwing it hard is much more safe than practically any other grenade, since the ThunderStrike V2 Flashbang weighs only 80-90 grams, depending on print settings.
Don't leave the mechanism cocked when not in use. Avoid dry-firing.
