Since people wanted to see how it turned out. This is a 330x330 object that covers the entire purported print area of my machine.
I’m ashamed to admit that I undershot my filament usage calculation slightly, and I chickened out just before the finish line. I didn’t have any more white in stock, so I switched to some grey of the same type from the same manufacturer by doing a mid-air refuel, shoving the end of the new spool in chasing behind the very tail of the old one. I don’t think it looks too bad. I may just spraypaint the entire thing white later anyhow. I wanted to use a light color in order to more easily spot and keep track of screws and springs and such.

I am impressed that the edges of your build plate are hot enough to keep the corners from curling up. This is a problem I fight on any print that is close to an edge.
A cooler bed can prevent warping. But a warmer bed may be better for overall plate adhesion.
I can’t speak for other printers, but my X-Max 3 has an absurdly thick aluminum plate under there which seems to spread the heat pretty well. I’ve poked it with my little IR camera and it’s not 100% even but it’s not bad. The only side effect of this is that it takes a month of Sundays to fully reach temperature, especially when you’re aiming for higher temperature materials like ABS.
Here it is on today’s preheat for PLA:

Wow, now i would really like to try a 256 mm³ cube on my A1 :D but this seems very unnecessary :D
Edit: Also a question: whats up with the yellow-ish colour in the upper half, is this the blemish you were talking about?
That’s just the shadow cast by the gantry blocking the LEDs that are all arranged along the front edge of the machine.
Rather, I have two of these which are just tiny specs of grey or black or grey or something, which got printed right into the top surfaces. They’re small, but annoyingly visible. This is what I get for buying cheap filament, possibly.

That’s a cube measuring ~6.5mm x 6.5mm x 6.5mm…I know the A1 is small, but that seems fairly unambitious.
Fuck you right. 😂 Damn you, volume law! I mean 256 mm * 256 mm * 256 mm (so more like 16,7 Million mm³)
If you go for something like lightning infill of 15% and 3 walls, you could probably make that print in something like 11h and only use 750g filament.
If there were ever a poster child for printing something with a 0.4mm layer height of possibly even more, it may be this. One wonders how much infill you’d need to make it strong enough to sit on. Otherwise, I don’t know what the heck you’d do with it.
If you’re a “regular sized adult” I honestly think you can get away with 30% adaptive cubic, and 5-6 walls and top/bottom layers.
That’s pushes it to 2.4kg filament and a +2 days print though with a regular 0.4mm nozzle and 0.3mm layer height.
Sounds plausible to me. On reflection, I think I’d just run off a wooden box on my table saw if I need a cube to sit on.
My problem, as I’m sure many others have, is admitting when 3D printing something probably isn’t the best solution…
There are many good applications for FDM printed items. But I still have a metal lathe, mill, drill press, and welders for all the other times that FDM is a poor choice.
