About this model
This is a 3D scan of a Classic Mini A+ (A-Plus) differential, captured on my own equipment with a blue light laser scanner and shared here completely free for the community. Unlike a designed-from-scratch CAD model, this is real-world geometry pulled straight off an actual A+ diff — so it carries all the genuine dimensions, casting shapes, and surface detail of the part as it exists in the wild. That makes it a useful reference for a whole range of projects where you need to know exactly how the diff sits, mates, and fills space without having a physical unit on the bench in front of you. A few things people tend to use scans like this for: Fitment and clearance checks — drop it into your CAD assembly to verify clearances when designing brackets, mounts, sump modifications, or drivetrain packaging Reverse engineering reference — pull key dimensions and surface profiles to model your own mating parts Visualization and planning — great for renders, build planning, or just understanding the geometry before you tear into a gearbox rebuild Educational / documentation — a tangible digital record of A-series transaxle internals for anyone learning how these drivetrains go together A quick note on what this is and isn't: a raw blue light scan captures the as-measured surface of the part, so expect organic mesh geometry rather than clean parametric solids. It's intended as a reference and visualization aid, not a print-ready functional replacement component. If you're planning to machine or manufacture anything critical from it, always verify against your own physical measurements — scans are an excellent starting point, but nothing beats calipers on the real thing for tolerance-sensitive work. I scanned this myself and I'm putting it out there for free because good reference geometry for these old British drivetrains is genuinely hard to come by. If it saves you some bench time or helps a build along, that's exactly what it's here for. Enjoy, and feel free to share what you make with it.
