Description
A snap-on directional air deflector designed to fit standard 10x10cm ceiling vents. The angled blade redirects downward airflow horizontally across the room, preventing direct drafts over specific areas like workstations and desks. The base attaches directly to the vent housing using integrated flexible geometry.

A custom 3-inch 3D-printed duct that transitions two side-by-side 120mm DC fans into a single 4" x 10" vent hole. Designed to straddle a wall stud right at the exit, it features an internal flow-splitting wedge to manage turbulence and a severed mounting flange for flush installation. Specifications Intake: Two 120mm fans (25mm thick) with integrated 1/4" mounting bosses Exhaust: 4" x 10" rectangular output Clearance: Central notch accommodating a 3.36" x 1.5" wooden stud Mounting: 20mm perimeter flange on three sides with 4.5mm wood screw holes Wall Thickness: Uniform 1/8" (3.175mm) throughout

A clean, three-piece ceiling canopy designed to bridge a jagged hole and manage a pendant cable. The mechanism borrows from standard flat-pack fixture hardware: a central core hangs from the ceiling hook and threads through the main cover, while a hex nut clamps the cover tight against the drywall. The core is hollow to let your two-wire cable pass through cleanly, with side-exits at the top so the wiring doesn't foul the hanging eyelet. Features 105mm Canopy: Leaves a comfortable margin over an 80mm hole to hide chipped plaster. Hollow Core: 8mm internal channel easily clears standard twin-core lighting cable. Thread Clearance: The nut is cut with an oversized 16.8mm thread for a smooth, bind-free fit on standard FDM prints. Support-Free: All three pieces sit flat on the bed and require no supports to run.
A robust, high-flow duct adapter designed to transition a standard 125 mm round bathroom exhaust duct into a low-profile 220 × 90 mm rectangular flat channel. The design features a pronounced vertical offset to navigate tight ceiling or wall spaces without compromising airflow. What it's for This part connects two dissimilar ducting systems. It is strictly female-to-female, intended to slip over an existing 125 mm round male pipe on one end and accept a 220 × 90 mm flat duct on the other. The 72.5 mm vertical offset is specifically tailored to align the flat duct closely to a wall or ceiling plane while maintaining the round pipe's original centerline. Dimensions Round Socket: 126.5 mm inner diameter, 30 mm deep (includes a 1.5 mm entry chamfer for easier fitting). Flat Socket: 222 × 92 mm internal dimensions with 5 mm corner radii, 30 mm deep. Overall Dimensions: 220 mm total length, maintaining a continuous 2.4 mm wall thickness. Offset: Centerline shifts vertically by exactly 72.5 mm over a smooth 160 mm internal transition. Print notes Print this model standing upright on the round flat face. No supports should be necessary for the interior loft, as the transition angle is steady and fully convex. PETG or ABS is highly recommended over PLA for HVAC applications, as the exhaust air and environmental moisture can deform standard PLA over time. Ensure your slicing profile is set to completely fill the 2.4 mm walls (usually 3 perimeters depending on nozzle size) to keep the assembly watertight and structurally sound.
An FDM-optimized structural adapter for mating a 100 mm circular duct to a 200 × 60 mm flat rectangular duct. Designed entirely through lofted profiles, the core internal geometry preserves precise clearance offsets before applying a constant outward shell. Continuous S-curve loft: Matches horizontal slopes at both sockets to eliminate turbulence edges. Built-in offset: 25 mm vertical eccentricity pushes the rectangular trunk higher than the round inlet axis while maintaining horizontal symmetry. Constant wall: Outward geometry maintains a uniform 2.4 mm thickness down the full 220 mm length of the part. Integrated chamfer: A 1.2 mm guide chamfer at the circular entry eases assembly of tight-fitting duct sections.
A parametric, FDM-printable ventilation duct adapter connecting a nominal Ø100 mm round duct to a 200 × 60 mm rectangular duct. Round Inlet: Ø101 mm internal diameter, 30 mm deep Rectangular Outlet: 201 × 61 mm internal, 30 mm deep Offset: 25 mm vertical centerline shift Wall Thickness: 2.4 mm (constant, pushed outward) Total Length: 210 mm (150 mm transition) Both ends are female sockets designed for a slip fit over existing plastic ducting. The loft provides a smooth internal airflow path with no steps or constrictions.

A plain ceiling canopy is a missed opportunity. When plaster tears out around a fixture box, a flat plastic plate covers the hole but looks entirely utilitarian. This canopy adds an intricate eight-fold radial bas-relief across the visible face, drawing the eye away from ceiling imperfections. Specifications Canopy Diameter: 105mm — wide enough to span a ragged 80mm drywall cut. Ornament Height: Raised 1.2mm off the base surface. Thread Interface: Generous 16.8mm internal thread on the canopy nut prevents binding when threading onto the core hanger. Printability: The entire assembly, including the filigree, sits flat on the build plate and requires no supports.
