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 lip. 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 flush, or the printed variants, fixed cups or tilt cartridges on filament hinge pins, both finished with a snap in trim ring that locks the lamp captive. All rounding is squircle style with continuous curvature and exact superellipsoid corners; past the physical cap the exponent relaxes toward an ellipse so the shape keeps getting rounder, and the bar height compensates for the roof curvature above the fixtures, so recessed fixtures fit at any rounding. Spot cutouts are confined between the walls, so small bar depths can never bite the fascia. Flat back, sharp bottom edge, service windows behind the spots. Segments join with one printed dovetail key per joint and glue. 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 lip. 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 flush, or the printed variants, fixed cups or tilt cartridges on filament hinge pins, both finished with a snap in trim ring that locks the lamp captive. All rounding is squircle style with continuous curvature and exact superellipsoid corners; past the physical cap the exponent relaxes toward an ellipse so the shape keeps getting rounder, and the bar height compensates for the roof curvature above the fixtures, so recessed fixtures fit at any rounding. Spot cutouts are confined between the walls, so small bar depths can never bite the fascia. Flat back, sharp bottom edge, service windows behind the spots. Segments join with one printed dovetail key per joint and glue. The printed cups descend from mick/lamp-fittings.
What you use it for
For recessed fixtures: set saw_diameter, ring_diameter, ring_thickness and fixture_depth from the fixture; the bar height follows automatically, including extra headroom when the rounding curves the roof down over the fixtures. For the printed cups or cartridges: twist the lamp into its socket, then press the trim ring (part = trimring) into the bore until it clicks. Printed cartridges and trim rings always show in silver in the preview because they are real parts; show_fixtures only toggles the grey lamp and fixture dummies. Print the segments; each cut carries one dovetail key with a 0.15 mm allowance. Glue the mating faces and slide the segments together from the front. Wire in parallel through the service windows and hang the bar on the keyholes. 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 squircle exponent is four until the rounding reaches the cap set by depth and height; past it the exponent eases toward two, morphing squircle into ellipse so extra slider travel still reads as more rounding. The automatic height adds the sagitta of the interior roof at the fixture position, computed from the effective radius and exponent, so cranking the rounding raises the bar instead of squeezing the fixtures. Corners are exact superellipsoid polyhedra, the shell is clipped to its bounding box, the cavity to the plate, and the bottom opening is a true inward offset of the outer footprint. All spot cutting volumes are intersected with the space between the walls. part = segment exports one segment on its back, part = cartridge the tilt cartridge, part = trimring the snap ring.
Parameters
fixture picks the spot mounting; saw_diameter, ring_diameter, ring_thickness, sink_rings_flush and fixture_depth describe a recessed fixture. width, depth, height and spots size the bar; height grows automatically when too small for the fixtures, including the rounding headroom. corner_rounding, front_lip, bottom_rim and body_color set the look, print_segments and wall_thickness the print, segment_number picks the exported section, and cutaway plus show_fixtures control the preview. tilt_range, preview_tilt and socket_screw_distance only matter for the printed spot variants.
