Libra Double Barrel 40wad Launcher - P1S/A1 Compatible Mashup

I really like the handle on the Jury-Rigged Boomstick remix Shirley Productions did on their original Libra, but preferred the barrels on the original, so I mashed those two frames together and it's a banger. Barrels were also too large to be printed on my P1S so I modified them to be P1/A1 compatible. A handful of other QoL (at least for me) improvements made to a few parts. 

Full changelog:

• Grip, baseplate, and loop from the Jury-Rigged Boomstick merged with front frame of the OG Libra to accept OG barrel geometry
• OG Libra barrel shortened to fit Bambu P1/A1 build volume, rails adjusted so they're still usable
• Barrel Lock lever shortened and geometry modified - I kept bumping the OG release lever with the edge of my hand unintentionally. Removed that material, reversed the hook (found this worked better for me) and made the spring hole on the bottom bigger to accommodate a wider variety of springs. You can still use the OG lever if you prefer that.
• Cut a spring cup into the firing pin - All of my springs were reaching max compression before the pin was out far enough, this fixes that.
• I prefer SBS triggers, if you want to do in-line ones you can get those from the Files tab in the original posting
