Old one broke... so i designed a better and robust mount (maybe a bit overkill ;-)  )
 I replaced the old domed screws with flat head ones. And to reinforce the mount, i have 8 inserted long m5 Machine Screws.  
I also shifted the Pin holes, to reduce the posibility of cracks(which should not happen with printed part in these orientation).

Instead of throwing away the Corner cabinet, or not be able to use IT, my Mother in law ask me to make the Magic Happen. How could i dissapoint her ;-)

Have fun, and Happy printing
