Improve printability of bins by using chamfers in corners

[lutorm]

I'm getting quite a bit of upturned corners when printing the overhanging, filleted corners of the bin bases. I think if these were chamfers instead of fillets this would be less of a problem, and it would not affect the stacking of the bins into the base.

At this point rounded corners are the standard. They should print well, I would try tuning print settings to see if that helps, very often issues on overhangs mean too high flow setting or too high speed.
