XShot Motorized Piston Pump id Barrel Shroud

This is a barrel shroud for the XShot Pro Motorized Piston Pump. It adds a top Picatinny rail, M-LOK slots on the sides and bottom, and points for a ball detent sling point (untested). 

For a 0.4mm nozzle w/ 0.2mm layer height:
- 5 walls, 3 top/bottom
- No supports
- 20% infill, I used rectilinear
- I used PETG but PLA is probably fine
- Print with the end of the shroud (facing the scar) on the buildplate

You will need:
- 4x M3x8mm SHCS screws
- Some kind of tape (optional)

Installation instructions:
- Install the M3 screws in the four screw holes at the base of the shroud so that they are barely showing on the inside of the shroud.
- (optional) Cover the part of the barrel collet that the screws will contact with some tape to prevent scuffing the plastic.
- Slide on the shroud and hold it against the front of the blaster so that it is snug.
- While holding the shroud, tighten the M3 screws enough that the shroud does not slip.
