Godwin pattern bolt pistol cosplay prop (smaller one)

This the smaller of 2 bolt gun props I've made, and is intended for normal human sized characters like the Militarum officers and the sisters of mercy. check my other uploads for the bigger one. 

I used a large format printer with a 0.8mm nozzle, but it still took several days to complete.

I recommend printing with a smaller nozzle to improve fitment of parts.

I sliced with Cura with no less that 3 perimeter layers and matched the top and bottom layers to that number, but this number will need to be increased for smaller nozzles. I used a 15% cubic subdivision infill. I use tree supports for ease in debridement. 

Total plastic used was well over a kilo. 

Trigger light:

The trigger has space behind it to install a momentary switch and a return spring, which is attached with hot glue in the groove in the slotted end of the trigger, and wired into a cheap flashlight installed behind the barrel. I don't know what parts you have available, so I wont be including a guide for wiring the switch. make sure you have a functioning switch installed on the trigger, wires attached, and free sliding motion of the trigger before gluing the lower halves together around it. take care not to glue too close to the trigger well, any glue that seeps into the trigger well will freeze the trigger in place, rendering it useless. 

This same trigger can be used for any electronic effect that you wish to include in your prop, but for the sake of simplicity, mine only has a simple light. 

Sliding bolt:

The sliding bolt gets inserted into the breech from the outside, and slid into the back position, then the bolt stopper is attached with glue or epoxy to the front inside surface of the bolt breech, closing the opening just enough that the bolt can travel its full distance without falling out. connect a return spring from the inset hook on the front end of the sliding bolt to the spring hook inside the upper shell's right side. this will hold the bolt forward, while still allowing it to be raked back for dramatic effect. 

Removable magazine:

There are small round recesses made into the faux “bullet” in the top of the magazine that are appropriately sized for neodymium hobby magnets in the size most available from Walmart. Any strong magnets that fit will suffice. they need to protrude from the plastic just slightly in their center to make contact with the steel inside the mag well. For this steel, I used a ¼" steel rod that fits into a hollow shaft in the mag well, but a small steel plate could also be epoxied onto the flat surfaces on the ceiling of the mag well if a rod is not available.  For better retention and no rattling, you can attach the loop side of some self-adhesive Velcro to the inner sides of the mag well, to hold more firmly onto the magazine. 

The two halves of the lower are epoxied together around the trigger, taking care not to glue the trigger in place. 

The barrel is epoxied into the foregrip so that its front surface is flush with front surface of the chain ring. 

The top rail and upper sides get epoxied together after printing. use the barrel part as a guide for shape. 

The completed upper assembly is attached to the lower assembly by 4 small flathead wood screws in the holes provided. 

DO NOT glue the upper onto the lower. you will need to change your batteries sooner or later. 

I put a lot of thought and a lot of hours into this. If you love it, drop me some coins.  

and please post your makes! I love to see my work blossom!
