Cycloneshock Nerf Blaster Priming Handle

thingiverse

My son was having trouble priming the Cycloneshock Nerf Blaster so I made this to help him out. It requires solvent welding four 3d printed pieces to the blaster itself, but does NOT require disassembling the blaster. The priming handle reduces priming effort by approximately 50% due to the linkage. Parts Required: (4) arm_v1 (2) hinge_connector_base_long (4) hinge_connector_base (1) handle (8) hinge_connector_cap (8) small screws (Mine measure 8mm long x 2.5mm to outside of threads) (8) M2.5 washers I used acetone/ABS slurry to solvent weld (4) of the hinge_connector_base pieces to the blaster. The exact location doesn'tn matter too much, just get it close to where I have it in the picture and make sure both sides match. Each of the joints at the blaster attachment points attaches with a hinge_connector_cap over a hinge_connector_base. The handle attaches with a pair of hinge_connector_bases as well. The midjoint connects using two hinge_connector_long, and two hinge_connector_caps For those interested, the source openscad files for the parts are available for everything except the arm_v1 part, which was cobbled together in sketchup (file also included)
