Now that is the $60 question, to make it flexible but strong what you would ideally do is print it so the layers would be upright, in other words print that shell on end. That could of course be done, but would make it difficult to make the ends look good. Probably the best solution would be to print the sides/roof standing on end and then print the ends separately and glue them into place after printing.
If printed in the orientation shown (which that one was) the layers are horizontal on the tab and it is likely to break on one of the layers - which as I recall did happen on at least one model till I increased the thickness of the tab. This was of course printed on the Ender 3 Pro which is an FDM printer. If printed on a resin printer at the same thickness it would be pretty strong, in fact the sample I printed on my resin printer has never to date broken.
