STL Model Correction and Detailing

I have three separate sets of .stl files that need to be brought to production-ready quality.

• Set A (1 group of files) – fix geometry issues: non-manifold edges, inverted normals, stray vertices, or any other problems that would cause slicing errors. The final files must be watertight and clean so they import flawlessly into PrusaSlicer and Cura. Set A is made up of three major pieces which currently to not fit together acceptably. In addition, satellite modules need the addition of bayonet/socket joints to allow for easy assembly.

• Sets B & C (2 groups) – add specific features and surface detail that I will supply as sketches and reference dimensions. Please keep overall part size unchanged while integrating the new elements smoothly into the existing mesh. Set B needs bottom modification to accept our standard base including slot and indents for magnets. Set C needs new base mounting piece to fit current slot in model and match foot print of our current bases.

Acceptance criteria
1. All files open with zero repair prompts in Netfabb, Meshmixer, or similar verification tools.
2. Dimensional accuracy within ±0.1 mm of the referenced measurements.
3. Final deliverable format: original resolution .stl, with identical naming plus “_rev” suffix.

Tools such as Blender, ZBrush, SolidWorks, Fusion 360, or comparable mesh-editing software are fine as long as the end result is clean and ready for SLA/FDM production.

When you reply, focus on your experience handling geometry repairs and feature additions on .stl files for 3D printing—brief, concrete examples are more useful than a full proposal deck.
