Where is the official version of the file for the Z Axis Frame for the i3 MK2 Original?

I'm looking for the official dxf file (or other format) of the Z-Axis Frame for the Prusa i3 MK2 Original that is currently in the Prusa Research e-shop. I'm not finding it in any of the branches in the company github repository found here: [github.com]

I found a couple of older posts that point to Josef Prusa's personal github repository found here: [github.com]

1) Is this still the current revision that is used in production?

2) I'm getting errors trying to open this file in Draftsight, Solidworks and A360 Viewer online.

Any tips or advice would be greatly appreciated.

This file does not seem to exists..

None of the versions I have seen have power supply mount holes for eg, and who knows what else has changed.
