RH/LH Straight-Edge Part STL

I need two mirror-image parts—right-hand and left-hand—modelled and supplied as clean, watertight STL files ready for 3-D printing in a UV-stable plastic. The geometry is simple and entirely straight-edged; the only curves are the circular mounting holes.

Dimensions
• Overall: roughly 60 mm × 30 mm × 30 mm
• Mounting holes: sizes and positions are already set

To make your job straightforward, I’ll share sketches that show the mounting hole locations and diameter. Your task is to translate this into production-ready files, duplicate the design as a mirrored opposite for the second part, and verify that the final models are printable without supports or non-manifold errors.

Deliverables
• RH part – final STL
• LH part – mirrored STL, identical tolerances

Acceptance criteria
• Hole diameters and centres match the provided sketches within ±0.5 mm
• All faces are planar, edges sharp, and models completely manifold
• Files open error-free in PrusaSlicer or Cura

If you spot opportunities to improve wall thickness or add subtle chamfers that aid long-term outdoor durability, let me know before finalising. Otherwise, it’s a straight modelling job with clear references—you can start as soon as I send the sketches.
