A round flanged collar with a clean central bore and a stack of grooved rims. This is a compact circular fitting: a wide, gently domed top flange surrounds an open central hole, and below it the body steps down through two or three rounded, grooved rims like a short snap-fit or threaded collar. It reads as a functional grommet or pipe/cable pass-through — the sort of collar that seats into a panel or a roof/soffit opening, which fits the name (French for "under-roof"). Smooth, symmetrical and utilitarian, it's a print-on-demand replacement part or a component for a larger assembly rather than a display object. Print notes: • Print flange-down on the flat top face for a clean visible surface and easy bed adhesion. • The stepped rims may need dialled-in tolerances if they snap or screw into a mating hole; test-print and tune your horizontal expansion. • Use PETG or ASA if it lives outdoors under a roofline; PLA is fine for indoor fittings. • Skip vase mode — give it three or more perimeters so the collar stays sturdy under load.
