Obviously metal is a fluid and moves around when it get's hot enough. That's a design concern we have mitigated. Hopefully. (Is there a wink emoji here?)
Yes, as others have said - looks like a solid design and your comment about adjusting the tabs shows you are trying to anticipate the effects of heat, etc. What I wonder about is the snugness of the fit between the tabs and their slots. It seems to me that with repeated heating and other abuse, those tabs will end up slightly out of alignment with the slots, making assembly a bit harder - but if the slots were made slightly sloppy to begin with, I think the assembly would remain pretty easy (as in your video) for a long time. And of course, the user can tweak the tabs or enlarge the slots, if needed. My "lay-observation". Thoughts?
