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.
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.
Thanks! This might also be a bit of burning by the nozzle slagging behind. I also see that sometimes on my prints
Could be. Usually when that happens there's some variance in the surface, too, or some booger left behind. I didn't see that here but it's possible it simply got mashed flat back into the surface on the adjacent pass.
