About this model

A purpose-designed mounting bracket to cleanly fit a T7 compact heater unit into a Classic Mini — designed from the ground up to take one of the best compact heater upgrades out there and bolt it into the Mini's notoriously tight foot well area without the usual bodge of zip ties, generic brackets, and hope. If you've ever dealt with a tired, leaking, or simply missing original Mini heater, you know the appeal of a modern compact unit: better output, smaller package, and far easier to live with. The catch is always mounting it — the Mini gives you almost no room to work with, and nobody wants to drill a dozen exploratory holes in the bulkhead figuring out where it sits. This mount solves that. It locates the T7 heater securely and repeatably, in a position that works with the car rather than fighting it, so you can get the unit installed and plumbed in with a lot less head-scratching. Designed in CAD specifically around the T7 compact heater and the Classic Mini, so the fit is intentional rather than improvised. It holds the heater solid against vibration and the bumps of real-world driving, and keeps everything tidy in an area where space is at an absolute premium. Print notes — please read, this one matters: Use a heat-resistant material. This bracket lives next to a heater core carrying hot engine coolant, and standard PLA will soften and sag at those temperatures. Print it in PETG, ABS, or ASA for a part that'll survive the environment long-term. PLA is fine for a test-fit, but don't trust it in service. Strength matters here, so go generous: 4+ perimeters and ~40–50% infill for a stiff, durable mount. No supports should be needed depending on orientation — orient for layer strength across the load path where you can. 0.2mm layers are fine; this is a structural part, not a cosmetic one. As always, do a test fit before final assembly and check clearances against your own car — Minis vary, and 60 years of restorations, replacement panels, and previous owners' "improvements" mean no two are identical.
