While creating a custom Nerf Longshot, I realized it needed a trigger guard. I know that there are 3D printed ones that I can purchase from other sources, but I did not want to spend $15+ on something I could do a basic design on myself using TinkerCAD. Though it is not incredibly refined, it's squarish look fits with the aesthetics of the LongShot. Here are the details on the rest of the blaster this was created for:

This is my Nerf ShortShot CS-5.5 Fanboy Edition (cause lets all admit it, the front barrel/gun/whatever thing that made it a “LongShot”, REALLY sucks) . Though I am not deep into the Nerf modding community I like seeing some of the awesome mods that people come up with. I have taken what I think to be the best of old school modding, combined it with new school 3D printing, and thrown my own custom paint style and basic 3D modelling and put them all together for all the LongShot fans out there!

As with all my creations, thank you so much to all the people that have put their ideas and creations out there for the world to see, use, or print. I bow to your awesome creativeness.

I took his center bracket design and printed in PLA 10mm thick at 30% infill and it works fine. I also remeasured and created the upper spacers as well. The lower spacer is no longer needed due to the thickness of the center bracket. You will still need to make the bracket arms out of aluminum due to stress. The aesthetics of this mod are cool, the mechanics of getting everything to work smoothly, are a nightmare. I may try the reverse bolt sled idea on my next build, IF I ever try this again.

"Conquerror" Picatinny Toprail by DevilZmods. Another awesome design by a pro it fits like a glove if the shell is cut correctly. Unfortunately the part warped in the 110 degree sun while the paint was drying so the fit is now a bit off.

Basic Longshot Trigger Guard designed by me, because I didn’t want to pay $15 for a part that I could design myself. It’s not as a “special” as a Worker but it works well for me!
