Materials and methods

Additional Materials:
- 50mm Outer diameter 44-46mm Inner diameter pipe (polycarbonate or PVC): 480mm length
- 10mm acetal/delrin/nylon rod: 210mm length
- K25 Primary spring from Mcmaster or other large spring (1x)
- 44mm OD O-ring (1x)
- 16mm ID O-ring (1x)
- 16mm elbows (2x)
- small compression/extension springs (buy an assorted box)
- 16mmx2mm aluminium bar (2x 202mm lengths)
- 15mm copper pipe (150mm and 55mm lengths)
- 16mm PVC pipe (260mm length and 2x small stubbs)
- 20mm clear PVC pipe (~70mm length)
- M3/M4 Cap head and countersunk bolts of various lengths
- 5mm threaded rod (could use a cut down M5 bolt)

Overall cost of other materials is around Β£10 - Β£18 per blaster depending on part sources.

Make sure to print the Muzzle piece in a bright colour so that it doesn't look like a replica firearm.

Slots need to be cut in the 50mm pipe for the priming mechanism to work. I used a jigsaw, but you could drill a series of 7mm holes and file it out into a slot.

Is there a build guide for this? I'd like to take a crack at it. Did you print the parts in PLA?
