The prompt
Create a standalone dual-barrel enclosure housing for an optical sensor and emitter assembly, designed to mount directly onto a standard tripod. Overall Dimensions and Shape: - Main block is a solid rectangular housing measuring 80 mm wide, 50 mm deep, and 40 mm high. - The block features two distinct horizontal cylindrical hollow cavities passing completely through the depth (50 mm length) of the housing, spaced 40 mm apart center-to-center. Left Cavity (Sensor Barrel): - A stepped circular through-bore aligned parallel to the depth axis. - Front section is a 16 mm diameter cylinder extending 15 mm deep to accept an ambient light shielding shroud. - Middle section transitions to a rectangular pocket measuring 8 mm x 8 mm x 6 mm deep, precisely dimensioned to flush-mount a BPW34 photodiode package. - Rear section narrows to a 4 mm diameter circular wire-routing hole exiting out the back face. Right Cavity (Laser Emitter Barrel): - A circular through-bore aligned parallel to the depth axis. - Main chamber is an 18 mm diameter smooth cylinder extending 35 mm deep to fit a standard self-contained laser diode casing. - Front section features an internal M14x1.0 thread pitch extending 10 mm deep to accept an adjustable focus collimating lens ring. - Rear section narrows to a 5 mm diameter hole exiting the back panel for driver PCB power wires. Tripod Mount Base Feature: - Centered on the bottom exterior face of the 80x50x40mm housing block, extrude a solid cylindrical mounting boss that is 25 mm in diameter and projects 10 mm downward. - In the exact center of this bottom cylinder, cut a vertical threaded blind hole with a diameter of 1/4-inch (standard 1/4-20 UNC tripod thread specification) extending 12 mm deep. Finishing and Manufacturing Details: - Apply a 1.5 mm chamfer to all four sharp vertical corners of the main housing block. - Apply a 0.5 mm fillet to the outer circular lips of both front barrel openings. - Export as a clean B-Rep solid STEP file geometry.
