Print in PETG, uses 2 #8 screws.

this takes about 1:10 to print on my X1c in the orientation I set up on the printable file - this orientation will maximize flexibility of the arms, this model is primarily intended to support the flashlight by the batter cap, but does appear grippy enough to support it by any of the ridges (as of right now… after months/years of use it will likely soften up)
