This was the second object I printed, immediately after getting that good thinwall box:
The arch foot broke loose from the platform after it grew to about 8 mm, but that seems to happen with most of the DIY printers. Apart from the tangle produced by that flaw, the rest of the object came out essentially perfect:
The surface finish is rougher than I think it should be, but the dense zigzag infill on the two thicker solid walls of the box seems to disturb their outer finish; the two thinner walls have linear fill and are fine.

There’s no source code, as I used the original STL from Thingiverse.
