X-Shot Thrasher Internal Ex BCAR

The thrasher is an excellent blaster however it isn't quite accurate enough for me out of the box. The internal barrel is simple and there's lots of room in there, so let's stick a BCAR in there!

I originally wanted to put a version of Leedle's hardware free BCAR, but there isn't enough room for it without redesigning from the ground up, so I went for the Ex BCAR which is nice and compact.

Simply put, we take the 12.9x8° Ex BCAR, chop off the threaded bit, add an extension barrel to the front to fit the blaster's muzzle then add another bit of "barrel" to fit the dart guide that fits into the barrel-facing side of the flywheel cage. The fit is tight and the accuracy of the blaster is noticeably better, particularly with single shots as you might expect.

With the stock battery pack, this might do even better with a larger spin angle, so I might try remixing this using the 12° Ex BCAR - if there was a 10° I would have used that first.

Hardware required (same as the Ex BCAR):

9x F683ZZ flanged bearings. 

9x m3x10 button head screws.  

Assemble with bearings flange nearest to the screw head, as shown in photos. The design accounts for the bearings in this Orientation only. 

I actually used printed F683ZZ's from I can't remember where, because I had them lying around. It'll probably work better with real bearings, if anyone tries that let me know, and I'll update this if I get around to trying it myself.

Print as oriented, long barrel side down, with no supports and 15% infill or more if you like. I printed mine at 0.16 layer size because it's a bit "cleaner" but 0.20 would probably work fine as well. Mine is printed in Orange PETG because PETG is my preference.
