A few more details:
In a flex vat this big, 210 x 260 there is quite a bit of load! I had to reinforce the bottom plate going from 3mm carbon plate to 6mm. Also have had some issues with the FEP ripping on the corners of the vat walls. Overall though I'm happy with my vat design where the vat walls push down into the film to create tension.
I used slot nuts in the extrusion from mounting the projector that have set screws to hold them in place. This way I can have multiple sets and be able to record the resolution settings for the different sets making it easy to change.
