Dimensional Accuracy Test

thingiverse

Just a quick test piece. Pieces are designed with precision in mind. The smaller square fits exactly into the hole of the bigger square. On a well-calibrated printer/slicer combo, the pieces should fit together seamlessly. Hard to snap into place, but still fitting without bending a single piece. And equally hard to push out again as well. STL dimensions are quite small (10mm side length for the big square, 6mm for the small one, 1mm height). Scale up in X and Y dimensions accordingly, small tests won't give you much insight. Hint: Cura's "horizontal expansion" is key to compensating for material width. In Slic3r, it's likely called "XY compensation". I'm not familiar with Slic3r, so I don't know for sure.
