I added a couple small holes to attach a chain with a charm to a Nerf blaster for customization. Thank you Sillybutts for a great blaster!

Required Hardware: 

  • 1x M3 Nut

  • 1x M3x25 Bolt

Printing Notes:
I used 5 walls of 0.3mm thickness and 25% infill, but use your own judgement based on your needs andd your machine.

Instructions:

  1. From the bottom of the grip, add the M3 nut into the small rectangular hole. Mine was a tight fit, and I used a small flathead screwdriver and a hammer to gently convince the nut to move down to the bottom until i can see the full opening from the round side window. If your fit is not tight, you may use a very small amount of glue as not to impact the threads. 

  2. Insert your M3x25 bolt into the round hole and screw it about halfway through the large rectangular window.

  3. Hook your charm onto the bolt using a clasp or a small keyring.

  4. Gently continue screwing the bolt into the nut until you feel a slight resistance. The bolt should be sunken into the round hole enough not to feel it when holding the grip.
