I plan to generate a print estimate that is accurate to the second; this is called the SecondSavr after all. I'd also like to give the user the option to show HH:MM:SS.s or SSSSSS.s format. The seconds format is more compact (3/6/0/0/.0/s vs 1/:0/0/:0/0/.0/s, where the slashes shows when a new matrix starts). Doesn't really need the percentage at that point. I don't think "hmn I wonder what percentage my microwave has cooked the food at.", but instead "How long left till the food finishes heating up?".

Yes, the handle looks sharp. This is a function-follows-form decision, since I doubt this printer will actually be lifted and moved more than it is looked at.

I've gone for a sharper / boxier looking typeface for the countdown timer. The "0" character probably shouldn't have a slash through it so that it's easier to discern from 8, but it does seem that I can virtually see the display from the other side of the room:

I originally planned for the handle extrusion to be completely white, but there wasn't a lot of display contrast.

I think the handle will successfully stand-out-from-the-crowd whilst still looking clean and modern.

There's a sleek cutout for opening the front door.

Like the current Suspense concept, the walls are ceramic tiles. Stiff, flat enough, looks beautiful, non-flammable and cheap = makes 100% sense to use.

Perhaps I could even get some Amazon Alexa intergration too. The entire bar has LED matricies in it, and I'm only using half for the countdown timer. 

For an £800-900 box of parts, I think it looks good enough that such a price is justified.
