Rounded plate with rotatable mount (parametric); Adjustable mount for print cooling systems

This is a mounting plate for a rotatable object, e.g. a print cooling fan duct. It is parameterized by two mounting holes of a specified distance center-to-center and diameter in a plate with rounded edges. From this plate extends a specified number of attachment points characterized by their length and width in addition to the diameter of a hole that can be used for mounting something else, e.g. a print cooling duct or offsets or ... The number of interleaves is variable as is the spacing be
