Trilogy Shell Break Action FLP-02 Booster Remix (Nerf Shotgun)

Summery

This is a remix of ShoelessHistorians Booster blaster to take trilogy shells. I made this after I got partway into designing my own double barrel T pull prime springer for trilogy shells, and then gave up. I got a barely functioning prototype and decided to take the lazy way out, and stuffed the break action parts from my design onto Je's much more polished and well designed blaster. 

I'm currently of the opinion that silly shells are the future of nerf shell fed shotgunning, but I know there are people out there like me that still have a stash of clearance trilogy shells. This blaster is for you. 

Note: This does not have shell ejection, you will need to tilt the blaster while holding the barrel to dump out spent shells. If you want to try to add shell ejection that would be awesome. I tried really hard to come up with some kind of super simple but elegant shell ejection method with but ultimately just went without. 

If you would like step files or .f3d files message me and I'll be happy to provide them. 



Writeup/BOM/Build Guide for Trilogy Shell Break Action Booster Remix

Bill of Materials:

All of the stuff required for the regular Booster (except the brass)

PLUS:

M5x40mm Machine Screw

M5 Nut

M4x40mm Machine Screw

M4 Nut

8ish inches of 1/4 inch diameter elastic (IDK what mine is I think it's 1/4") 3mm should work too.

Sheet of Craft Foam (I think mine is 1/8 inch thick or close to it, you need around at minimum a 4 inch by 3 inch section)

Superglue

Xacto knife

marking tool (pencil, permanent marker, etc)

Printing and assembling this blaster should be pretty self explanatory, but I've explained it in detail below anyways.

PRINTING

Print all parts needed for the regular FLP Booster on printables. EXCEPT for the Bottom Rail, Front Rail, and Front. Also ignore all stock barrels/ attachments and whatnot.

Print the files in this zip. DO NOT USE SUPPORTS on the "Booster Front". It should be printed plungertube side facing down. Everything else use supports where you feel like it's needed. If you print the "Booster Front" with supports in the places where the plungertubes and O-rings are supposed to go you will not be able to remove them and you will have fitment issues. Your printer should bridge the gap easily. The "TRILOGY SHELL FRONT MUZZLE" should be printed tip down. Should not need supports on the elastic through hole either.

ASSEMBLY

Assemble Booster as normal using required hardware and build guide from the booster printables listing. 

Next take the "cutting guide" print and use it to carefully trace and cut out a matching shape of craft foam.

Then attach the muzzle ("TRILOGY SHELL FRONT MUZZLE") to the "Booster Front" Using an M5x40mm Machine Screw and fasten with an M5 Nut. Attach the "LATCH" to the muzzle with a M4x40mm Machine Screw and fasten with an M4 nut. Take your elastic, and tie a knot in one end. Cut off excess and melt the end with a lighter or other flame to prevent fraying. Probably do this outside so you don't breathe it in. Then push your elastic through the LATCH and out through the bottom of the TRILOGY SHELL FRONT. Tension the elastic and again tie a knot in it, cut, and melt the end.

Place your cut piece of craft foam between the Muzzle and the Booster Front, and place shells in. Check that everything seems to fit ok, the foam will compress slightly after some use. My shells I printed fit slightly looser than my stock hasbro ones, but both fire ok.

Unscrew the M5 Bolt and Nut and remove the muzzle assembly. Glue your craft foam onto the Booster Front using superglue. Be sure to get a thin layer of glue all around the holes in the Booster Front.

Let the glue dry for a couple hours, then re attach the muzzle assembly and test that the blaster can open and close properly. Trim any foam that gets in the way of this with the xacto knife.
