GryphEX BCAR

Made using epicxxxx's bearing centering and rifling device with changes to accommodate fitting to a Gryphon with Banned Blaster cage. A tapered guide was needed to feed the darts into the device. Turned the orientation of successive sets of bearings inline with previous. Filled the space in between with ports for less drag. Created a threaded base plate to mount the device. Needs 6x F683ZZ flanged bearings, 9x m3x10 button head screws, 3 of which mount the base. 

Prints without supports, 0.2 layer height, minimal infill
