The prompt
Create and save an early manufacturable CAD concept from the user's modular broom product brief: one repeatable 4.0 in x 2.25 in removable extension block, vertical slide-down male/female dovetail connection, 3D-print clearances, inspectable spring-loaded latch/button/spring cavity and receiving pocket, underside replaceable rail-mounted bristle cartridge with retention detent and representative tufts, plus two mated identical blocks and an exploded inspection copy. Not load-rated or production-ready.
