B7 foresight, emitter holder disc and bung.

thingiverse

B7 Fed Blaster parts needed to finish it off. A disc to hold the central IR emitter and red/green LEDs around the outside for muzzle flash. A reflective emitter housing is used to hold the emitter in the correct place. The emitter bung is to hold the emitter firmly in the emitter housing. You may need to adjust the emitter bung dimensions according to the size of your emitter and/or emitter housing, or your emitter housing may not require any additional bung. It depends. I have seen at least three different variations of the "standard" 5mm emitter housing. All fractionally different dimensions. The black foresight needs to be connected to the main body with a 6mm diameter fibreglass rod (around 250mm long, adjust to fit your preference of foresight extension). Colour the rod copper/brown. The red tube ring is to fit the fore-part of lens assembly, over the silver lens tube (see photo of fully constructed item).
