Bath Interferometer

Dale's Interferometer is great but it had 3 different screw sizes (imperial). I standardized on one size: M3 (metric 3mm) which I have tons of and are at my local home depot. Also I added a paper holder.

Some parts are stronger or need less material to print than original. Some corners were rounded so brim isn't necessary (e.g. the base).

I sell the metal parts for this or have information where you can get them and optical parts on your own. Also I have assembly and usage videos for this and the xyz table. All here:

All screw holes should be drilled with a 7/64th drill bit.
