Nerf Rapidstrike Battery Door Holder Retainer

Save those thumbscrews! It's crucial they're secured in place where the barrel extension would normally go, keeping the battery door stable and secure. You might consider having a screw handy if you're unsure about the print quality to ensure everything stays put. Don't worry about the supports shown in the photo; I left them on for now so I can anneal the part later. Those supports are there to safeguard the bump that guarantees a tight lock, but feel free to remove them and flip the object 180° if you don't need it. Future upgrades might involve reinforcing the entire tab that extends from the cylinder. This design still needs to be battle-tested!
