jet reducer
Mismatched pipe threads stop a plumbing job dead in its tracks. Instead of chaining together three different brass adapters and hoping they don't leak, this straight-shots a 1 1/4" male line into a 1 3/4" female fitting. The threads are cut straight (NPS style) with FDM clearance built in, so you will need a healthy wrap of Teflon tape to force a watertight seal. Total Length: 3 inches (76.2 mm) Wrench Flats: 60 mm across, giving a solid grip for a large adjustable spanner. Bore: 32 mm internal channel. Threads: ~11.5 TPI pitch, heavily offset to prevent layer-binding on FDM prints.
HexAdapt — Spa Jet Adapter
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.
Vileda Broom Hook Cap
A replacement end cap and hook for Vileda broomsticks, designed to press-fit over the internal mushroom anchor. Secure Fit: Internal cavity matches the 13 mm stepped mushroom anchor with a precise 0.5 mm tolerance. Large Loop: The tapering 30 mm hook radius easily clears 27 mm hanging bars. Smooth Profile: Completely rounded edges prevent wear and tear. Designed to be printed standing upright. Standard tree supports are required under the hook overhang. ASA or PETG recommended for the press-fit shell.
Eccentric Duct Adapter 125mm
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.
Eccentric Duct Adapter
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.
Compact Offset Duct Adapter
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.
