The prompt
Create a three-part parametric mechanical assembly for a medical device tablet applicator, shaped like a sleek mechanical pencil with an expanding-prong tip and a side-mounted slider button mechanism. All dimensions are in millimeters. Part 1: Outer Pencil-Shaped Sleeve - Structure: A hollow cylindrical tube, overall length 95mm, external diameter 10mm, wall thickness 1.0mm. - The Tip: The forward 15mm section must taper down evenly to a smooth, rounded nose cone apex with a 1.5mm fillet. - The Wings: The tapered nose cone must be longitudinally split by four perpendicular 0.5mm slots, creating 4 independent, flexible expanding segments ("wings"). - The Track: Cut a rectangular mechanical slider slot into the side wall of the cylinder body. The slot dimensions are 2mm wide by 15mm long, positioned 30mm from the rear end of the device. Part 2: Internal Actuator & Expansion Rod - Structure: A solid inner rod, 85mm long with a base diameter of 4.0mm, running through the center axis of the outer sleeve. - The Mandrel: The forward tip of the rod must expand into a conical wedge (mandrel) tapering from 4.0mm up to 7.8mm. When advanced forward by 12mm, this mandrel physically forces the 4 outer sleeve wings to flare open radially from a resting diameter of 10mm to an expanded clearance width of 13.5mm. - The Pin: Affix a perpendicular cylindrical mechanical pinning post, 1.8mm in diameter and 3mm long, perpendicular to the rod body, aligned perfectly with the outer sleeve's track. Part 3: Manual Control Slider Button - Structure: An ergonomic, low-profile thumb button designed to sit flush against the outer sleeve wall. - Dimensions: 12mm long, 6mm wide, and 2mm thick with a cross-hatched, high-friction grip texture on the top face and filleted outer edges. - Assembly: The underside of the button must feature a solid female receiving socket that press-fits securely onto the inner rod’s pinning post through the outer sleeve's 15mm sliding track. Ensure all tolerances maintain a uniform 0.15mm clearance to allow smooth, friction-free mechanical movement of the slider and clean radial deployment of the expanding tip without part binding. Export as a unified B-Rep STEP assembly.
