Polar scope cover for Atlas mount

Polar scope cover cap for Atlas mount. The sharp edges of the mount's aluminum thread destroyed the plastic thread of my original cap. As far as I know this is a common problem with Atlas mount. Two parts design limits the use of aluminum thread. The "mount_side" part stays attached to the mount while the second part is used to cover/uncover the polar scope.
I recommend printing at highest quality settings, otherwise the printer may fail to print threads accurately. If threads are too tight/loose scale parts in X-Y direction by a fracture of a percent.
