STL Surface Edit & Alignment

I have two STL files for 3D printing that need refinement. One model requires a small surface adjustment, then both models must be accurately aligned so they sit in the same coordinate space. After that, I want any rough cut marks or stray triangles cleaned up.

The end goal is to keep the files as separate printable parts that fit together smoothly once printed. Please preserve existing dimensions, keep each mesh watertight and manifold, and return the updated STLs ready for slicing. If you typically check tolerances or run test assemblies in Meshmixer, Netfabb, Blender, or similar tools, let me know—those steps are welcome.

Deliverables:
• Two cleaned, aligned, and surface-corrected STL files
• Confirmation that each file passes standard mesh integrity checks

I’ll supply the originals as soon as we start.
