Half-Round Arch Moulding Crest

A clean half-round arch, ready to crown a doorway, a mirror or a bar sign. The piece is a simple, elegant semicircular arc - a smooth rounded moulding that sweeps up and over in a true half-circle, then turns out into two short flat feet where it would meet a lintel or base rail. The profile is gently convex, so it reads as a soft raised bead of material rather than a flat cut-out, and the whole form is symmetrical and uncluttered. Think of it as an architectural accent: an arched surround for a door or window, the top rail of a headboard, a frame for a round mirror, or the upper element of a hanging shop or workshop sign. Its plainness is the point - it plays nicely with lettering or a motif set inside the arch. Cut & print notes • On the CNC, a round-over pass gives that soft crown; the flat feet make clamping and alignment straightforward. • Scale the span to your opening; the arc holds its proportions at almost any width. • As a 3D print, lay it flat and it needs no supports at all - the underside of the arch prints clean. • Pair two mirrored copies, or stack the arch over a straight rail, to build a full frame.
