Edit* let me rephrase that. Not stronger but flatter and more supportive over the whole plane.

Got a piece of 4mm glass cut to the size of the bed, driller the glass and the original bed with a 5mm hole and used appoxy to secure 5mm rare earth magnets into all holes.

I had to print a 5mm shim to raise the z axis end stop to allow for the extra 5mm added to the build plate.

Stuck a sheet of buildtak on the glass and to be fair that stuff is awesome. Since doing the mod my prints have improved 10 fold and removing the parts is a lot easier now I can remove the build plate.

You make four small corners that attach to the existing bed, with screws, and install a precisely cut piece of semi-flexible plexiglas. On top of this, you can put anything you want; I've used BuildTak here in the picture (and with residue glue).

Previously, BuildTak was gripping too much on my models, and if it was on top of the glass-plate on the Davinci bed, almost impossible to get out. Also, using a spatular, I had to use so much force I thought i might break the entire printer. However, with this, I just take off the plexiglas, and bend it just enough, to the models to loosen its grip.

There is a small bend in the plexiglas on the above image, from what i do think is when the materials contract - either that or I just forgot to "unbend it" last time i used it (i tend to bend it flat from time to time). However it has never caused an issue with my prints.

Really really simple mod, seen here below - just four pieces. I can find the .stl's as soon as i get access to my old computer again
