About the job
We print shoe uppers in foamed TPU (Recreus Filaflex Foamy) on Bambu Lab printers (H2D, 0.6 mm nozzle).
Our tool, 4meMesh, cuts a horizontal slit pattern into the upper skin at slicing time. The model we have, the StrideMule, is already split into the parts we need; what is missing is printability. Today's meshes hurt the prints: variable upper thickness (in one shoe, 12 % of the upper was thinner than 3 mm, where no sandwich
fits), open or self-intersecting meshes (one zone mesh had 1 043 non-manifold edges and the slicer silently ignored it), duplicated triangles (43 589 in one file), and slicer "gap infill" scraps that show on the surface.
We are asking for three things, and nothing else:
1. Printability of every part as delivered (same six parts, same names; do not merge, re-split or add parts).
2. Resize the whole shoe to the delivered last, last41.stl. This is a re-fit, not a uniform scale: the upper is
rebuilt as an offset of the last with the clearances of §4, and the outline of uppersole, midsole and
outsole follows the bottom of the last. After the resize, every rule of §4 is checked again on the resized
parts. Check the images in the Annex for reference.
3. Repair uppersole: it has two through-holes (heel and forefoot windows) and a notch at the heel. Rebuild
its top face as one continuous surface (keep the arch and heel-cup shape; do not patch the holes flat)
and close the solid. Check the images in the Annex for reference.

4. Repair the two we send (`Front_Side_Modifiers`, `Side_Modifiers`) on the resized upper, and **create a
new one, `Toeball_Modifier`**, over the toe box and the ball of the foot, following the outline we will
mark on a screenshot. All three as closed solids. Check the images in the Annex for reference.
