The file 'Nerf N-Strike Modulus XD Blaster Gap Bridge 3D Printer Model' is (stl) file type, size is 1.6KB.
The original shoulder part, which is delivered with the blaster, does leave an ugly open end and a gap that looks ugly. with this small part you will get a smooth look. Simply press the holding bars into the open end of the shoulder part. Might need a little bit of force, but therefor fits tightly.
