The 3D printable NEW VAT for the Bean would be a bit different & will look more like several of the DIY VATs. It will have to have a border all around the outside to be able to put screws there instead of the metal inserts they used on the plastic injected VAT.
* * * It would be too much trouble to add nests for metallic inserts on the top of that border as when you turn the VAT upside down to replace the FEP film they would never hold in place & all fall down. Better use HEX screws or other type of screws plus nuts to hold the foam gasket plus steel ring in place. On the 3D printable version they would have to increase the vertical wall of the VAT to compensate for the new external border thickness to fasten the screws.

*** They will have to calculate the shrinkage for the 3D printed VATs based on type of plastic used (PLA, ABS, glass filled plastic, etc) & will need to obtain the settings used on the FDM printer & if fan cooling was used, heated bed used or not, & so on, because the laser cut neoprene gaskets will have to include laser cut holes too for each of the screws emplacements on the VAT & the holes of the gasket will have to match the position of the holes holes of the VAT.
For the NEW injected plastic version I hope KUDO3D will adopt, one with gasket & hinges with real pivots, KUDO will not need to change the minimum shape of the VAT too much. Except for the new real hinges the other change that I see would be on the underside : it would be better & safer for KUDO3D to add 2 ridges connecting all the holes for metallic inserts instead of the single ridge you currently use. Those 2 ridges will help the gasket to provide a better barrier (a 2nd bartier) against resin leaks. The gasket will be pressed down directly against those 2 ridges. 2 ridges will be better than the single current ridge to provide proper sealing. It will also help to make the VAT a bit more rigid.
I am including a quick drawing to illustrate one of the 2 changes that is needed for VAT. Those 2 ridges will not only provide a better seal when/if they will (I hope) add a real neoprene gasket on top of them & will also add more rigidity to the VAT, which should reduce or eliminate resin leaks.
