Bath Interferometer parts

There is now a version 2 of this that has a few useful modifications. https://www.thingiverse.com/thing:2843786

These parts can be used to make a Bath interferometer used to measure telescope mirrors.
These parts were designed for a 15mm beam splitter, 7.6mm diameter lens, and 13.5 mm diameter laser pointer.

The parts were designed in Fusion360 and that model will be published. It has been parameterized to make lens and laser holders of different sizes.
