Omicron type sample holder box for 6 samples

Omicron-type sample holder is one of sample holder standards for scientific applications. It is basically a unified shaped plain metal (usually) plate of 21x18x1 mm in size. It may be put inside a sample preparation (sputtering, e-beam evaporation, molecular beam epitaxy, etc setups) or investigation (electron microscopes, ARPES, etc) machine, often under vacuum.

The presented thing is a slot for this kind of sample holders, which secures the sample surface and fixes it in space for storing and transportation. Max. sample height is 7 mm. Up to 6 of these slots are put together inside a larger box.

There are two slot models. One is harder to insert a sample. Before usage one should push a dummy sample holder inside (closer to the back side) and tilt/push with some force sideways to shape the "nest". Afterwards samples are fixed inside nicely. I printed mine in PETG and after a minute this worked fine. A loosen version is not tested yet and may be modified later.
