To make this fit into the hole for this

Nanox tube video exposes a problem with the fake 25 Nanox.Arc devices that Nanox claimed to have completed, and the 1,000 devices for which it claimed to have sourced all the metal parts.

Here are the holes for the x-ray tubes in the devices (3 shown, out of 5 holes).  Nanox never filled those holes with tubes.

And here is the new Nanox tube.

Nanox has to find a way to make this glass tube fit into the hole and housing (head) designed for the fake ceramic tube, which was shorter and which had an x-ray exit flange closer to the cathode end.  By just looking at it, drilling new holes, manufacturing an adapter, and repositioning (tilting/rotating) the tubes won't be enough - substantially the entire metal enclosure needs to be redesigned, manufactured, and reassembled.

NASA may have had an easier job.

"We gotta find a way to make this fit into the hole for this using nothing but that.”
