STL Repair & Dimension Tweaks

I have several existing STL models that need two things: first, all holes in the meshes must be fully closed so the files become 3-D-print–ready; second, a few critical features have to be resized to the exact dimensions I will supply once we start.

You’ll receive the original STLs, reference screenshots and a short table listing each feature’s current size and its target measurement. Once your work is done, I should be able to drop the files straight into Cura/PrusaSlicer and see watertight, manifold-free geometry with the updated dimensions reading correctly in the slicer.

Deliverables
• Cleaned, watertight STL files (no holes).
• Adjusted geometry reflecting the specified dimensions, verified by you in any common mesh-analysis tool (Meshmixer, Netfabb, etc.).
• A quick before/after summary noting the edits per file.

If you’re comfortable repairing meshes and making precise geometric tweaks, I’d love to get this wrapped up quickly.
