Tweeter cup

Inner diameter is ~45mm when printed. At this 3D-model inner diameter is 2mm bigger, but it shrinks about that 2mm when temperature lowers. I printed this with supports and cup pointing up with PLA.

Depth of this cup (where tweeter goes) is ~37mm, diameter at the finished product is 45mm. Wall thickness is about 1mm. Full lenght is ~66mm. It has two angles for the installation and installation holes(5mm but notice the shrinking).
