Description
A parametric conversion plate designed to adapt universal slide-in dust bags to a specific vacuum auto-empty dock.
The model provides a baseline structure with a central suction tube for the dock interface and C-channel rails on the reverse side to capture the cardboard collar of a generic bag.

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 precision-cut female adapter engineered to mate with non-standard 1.750" (44.45 mm) hot tub and spa jet threads. Bypassing the conventional 1.5" nominal standards, this design is bored out with exact clearances tailored for ASA shrinkage and layer lines. Dimensions Female Thread: 44.45 mm base major diameter + 0.3 mm radial clearance (45.05 mm total cut). Pitch: 12 TPI (2.116 mm). Interface: Standard 1.5" flexible hose barb (38.1 mm core, 42 mm ridges). Wrench Drive: Heavy 64 mm hex. Print Notes Oriented flat on the hex base. No supports required. Designed with 0.3mm added radial clearance, making it ideal for dimensionally accurate ASA prints without post-processing.

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.
