mesh2cad 0.13.0 exports the Prusa MK3S Y motor holder as an editable OpenSCAD and CadQuery script. The old approach intersected full-length silhouettes and missed by 7.9 mm. A union of partial-depth extrusions gets it to 0.18 mm.

mesh2cad 0.12.0 makes all six real Prusa MK3S test parts exact STEP solids and exports the belt idler as an OpenSCAD and CadQuery script with named hole, chamfer and depth parameters. Two parts are still refused, and the refusal says why.

You converted a STEP file to STL. The preview looks right. But "looks right" is not a check: a mesh...

mesh2cad 0.11.0 turns three more real Prusa MK3S parts from STL back into exact STEP solids. The fix only worked after I checked my own diagnosis against the original CAD files and found it was wrong.

mesh2cad 0.10.0 writes the Prusa MK3S endstop block as the intersection of its X, Y and Z silhouettes plus a counterbored hole, so the OpenSCAD and CadQuery scripts have parameters you can actually change. How it works, real numbers, and the four parts it still refuses.

mesh2cad fit planes and cylinders perfectly on my own test meshes and fell apart on six Prusa i3 MK3S parts. What was different about CAD-exported STLs, what 0.8.0 and 0.9.0 fixed, and what still doesn't work.
