Work stand upside-down for original Prusa MK3 / 6mm Frames

A simple frame stand for the original Prusa i3 MK3 or other printers with a 6mm frame.
I designed it for easier work on the bottom of the printer.
Could come in handy, but probably not. Anyways, here it is :D
Edit: I actually needed it after my y-Belt tore, hooray!
