The prompt
Create a 3D printable mechanical enclosure in two separate parts. Part 1 (Main Tube): A hollow cylinder with an outer diameter of 86mm and a wall thickness of 2.5mm. The interior cavity must feature an internal ledge with an inside opening diameter of 79mm, creating a shelf to support an 80mm circular circuit board. Above this shelf, the main internal cavity diameter must be exactly 81mm. Cut 4 symmetrical, evenly spaced female bayonet locking slots along the upper inside rim. Each slot needs a 3mm wide vertical entrance channel and a 3mm high horizontal locking track. Part 2 (Quarter-Turn Cap): A circular cap with an outer rim diameter of 86mm and a thickness of 3mm. On the interior side, include a plug section with a diameter of 80.6mm extending out by 8mm. On the perimeter of this plug, place 4 matching male bayonet locking tabs that are 2.6mm high and protrude outwards radially by 1.3mm to fit perfectly into the Part 1 locking channels with built-in clearance tolerances. Export the final output as a watertight, slice-ready STL file.
