A modern wall mounted light bar for above a bathroom mirror. Three GU10 spots point down through the recessed bottom plate, hidden behind the front fascia so you see a clean bar and the light washes over the mirror. The fixture parameter picks how the spots are held: store bought recessed GU10 fixtures that clamp into round cutouts with their own spring clips and tilt mechanism, optionally counterbored so the bezel sits flush with the plate, or the printed variants, fixed cups or tilt cartridges on filament hinge pins. The bar automatically grows tall enough for the recess depth. The back is flat against the wall with rounded top corners that blend into the spherical front corners; one rounding radius, sharp bottom edge, service windows behind the spots, and a bottom opening that follows the outline with rounded front corners and a very subtle 3 mm ease on the back corners. Segments join with printed dovetail keys and glue: no dowels or other hardware. The printed cups descend from mick/lamp-fittings.

What is this
A modern wall mounted light bar for above a bathroom mirror. Three GU10 spots point down through the recessed bottom plate, hidden behind the front fascia so you see a clean bar and the light washes over the mirror. The fixture parameter picks how the spots are held: store bought recessed GU10 fixtures that clamp into round cutouts with their own spring clips and tilt mechanism, optionally counterbored so the bezel sits flush with the plate, or the printed variants, fixed cups or tilt cartridges on filament hinge pins. The bar automatically grows tall enough for the recess depth. The back is flat against the wall with rounded top corners that blend into the spherical front corners; one rounding radius, sharp bottom edge, service windows behind the spots, and a bottom opening that follows the outline with rounded front corners and a very subtle 3 mm ease on the back corners. Segments join with printed dovetail keys and glue: no dowels or other hardware. The printed cups descend from mick/lamp-fittings.
What you use it for
For recessed fixtures: set cutout_d, bezel_d, bezel_t and recess_depth from the fixture; the bar height follows automatically. The preview draws a grey dummy of each fixture at full recess depth; show_fixtures toggles the dummies and they are never part of a print. Print the segments; each cut carries three dovetail keys with a 0.15 mm fitting allowance, so the parts align themselves. Apply glue to the mating faces and slide the segments together from the front. Push the fixtures into their counterbored cutouts from below until the clips grab, wire them in parallel through the service windows, feed the mains through the nearest window and hang the bar on the keyholes. For the printed variants: cups are fixed, cartridges tilt on 1.75 mm filament pins secured with glue or a melted head, and gu10_hole_span must match your bare socket. LED GU10 lamps only, PETG or ASA for a bathroom, out of the shower zones, and have the mains connection checked if you are not certain of it.
Design notes
The segment cut is not a flat plane but a comb: three dovetail keys extruded through the depth, one running through the glue boss on the plate, one through the walls at mid height and one through the boss under the top wall. The flare of the keys locks the joint in width and height, the only free direction is the sliding one, and the glue closes that. Sockets are grown by 0.15 mm so printed parts actually fit. The flush seat for a recessed fixture works with a local boss: the plate stays 3 mm, a ring one bezel thickness tall sits on top and the counterbore leaves 3 mm above the pocket floor, so the spring clips clamp the same thickness as a plain plate. The shell is one convex hull with a flat back plate with rounded top corners blending into the front corner spheres. Keyholes sit in the columns between the service windows, offset from the cuts. part = segment exports one segment on its back; part = cartridge exports the tilt cartridge.
Parameters
fixture picks the spot mounting; cutout_d, bezel_d, bezel_t, flush_bezels and recess_depth describe a recessed fixture. total_width, depth, height and spots size the bar; height grows automatically when too small for the fixtures. rounding, lip, rim and color_body set the look, segments and wall the print, and cutaway plus show_fixtures the preview. The last group only matters for the printed spot variants.
