Hitachi TM3000 Sample Height Gauge

We have a Hitachi TM3000 table-top SEM at work, but someone lost the gauge that lets you set the sample holder to the correct height for the unit to be able to focus on your sample.

I finally found one and measured the height of the gauge. With that info, I made up a similarly-shaped model so that I can print more as they lose them.

The file is designed to print without needing supports. We're currently using 10% fill, 2 shells, and an 0.2mm layer height.
