I made and cleaned a "U Holder" to independently individual bowtie subassemblies like the piezo assembly. This U Holder has a counterbored hole for a #8 screw to go into a post or pedestal. Screwing into a 1 inch or 1.5 inch diameter pedestal requires a 0.5 in diameter spacer, which I have ordered from Newport. The height from the mounting point of the U holder to the center of the mirror is 1 inch.
After cleaning, I did a fit check, and the piezo assembly base screws into the U Holder.
Attached is the model I used to make this part. I did not add the vent grooves. The V2 longer version I ordered from 3D Hubs is better as it is compatible with more mounts. In addition, this part should be steel so it does not flex as much when there is weight on one side.
