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.
Vented De Quervain Thumb Splint
A rigid thumb and wrist splint designed to immobilise the base of the thumb during de Quervain's or "texting thumb" flares. A continuous moulded bridge locks the thumb and wrist together, preventing the specific joint articulation that aggravates the condition. The C-shell design allows the splint to slide onto the arm while maintaining structural rigidity. Includes two sizes (Small measures 140mm along the forearm with a 45mm thumb post) Grid ventilation cutouts across the forearm and thumb regions to improve airflow Four integrated routing slots sized for standard Velcro tension straps Open medial cutaway for easier fitting and removal Print with adequate perimeters for rigidity. The interior clearance accounts for standard dimensions, but rigid braces benefit from a thin layer of foam padding or a fabric sleeve worn underneath to prevent skin chafing during extended wear.
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.

Tolerancia: Tiene un chaflán perimetral de 0.4 mm para facilitar la inserción y evitar rebabas en la primera capa.
Yard Game Clothespin Scoreboard
A lawn game scoreboard that uses standard clothespins on the outer edge, skipping complex slider mechanisms. Player one and two tracks run entirely opposite colours at every number, forcing high visual contrast across the gap. Print Envelope: Split exactly at the 10/11 mark into two 242 mm halves to clear standard 256 mm beds without resizing. Assembly: Halves join via a structural rear half-lap held by M3 or M4 bolts. Colors: Designed to run standard alternating black and white to keep counts legible from a distance.
CluckFlow — Gravity Waterer Cap
New chickens bring endless questions, but a reliable water supply doesn't have to be one of them. CluckFlow is a gravity-fed waterer cap that threads directly onto a standard bucket or heavy-duty jar, instantly converting it into an automatic hydration station for the coop. A smart internal drip-feed port regulates the flow from the main reservoir, ensuring the trough automatically refills as the hens drink without ever flooding. Dimensions Trough: 40 mm continuous drinking width accessible from all sides. Central Feed Tube: 20 mm inner diameter. Collar Thread: 100 mm diameter with a 5 mm pitch, scaled for common bulk containers. Design Features Print-in-Place: The internal bell funnel is steeply angled to bridge the gap between the central feed tube and the outer threaded collar, printing entirely without supports. Self-Regulating: Multiple drip ports ensure constant equalization of the water line.

Textured Handle: Raised grip rings ensure secure handling. Printable Size: Scaled down to fit comfortably within a standard 250mm build volume.
Ornate Bas-Relief Ceiling Canopy
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.
Deep Trough — Single Feeder
A deep, single-volume wire cage feeder. This updated design drops the middle divider and front perch to maximize internal volume. Perfect for dispensing large amounts of dry feed or hay. Dimensions Width: 3.5 inches (89 mm) Depth: 5 inches (127 mm) Height: 3 inches (76 mm) Features Heavy-duty S-hooks integrated into the rear wall Rounded internal corners for easy cleaning Thicker base (2mm) for durability

Allows connecting combustion engine grill fan to a pk360 grill intake vent
86mm Windowsill Tomato Seedling Tray
12-cell starter tray dimensioned for narrow residential windowsills. Fits a standard 86mm or deeper sill plate. Do not attempt to balance this on half-depth ornamental ledges; the 253mm overall length requires a completely flat run to avoid stressing the joined top lip when loaded with wet soil. Fitment Specs Clearance Required: 86mm (W) x 253mm (L) minimum flat sill surface. Cell Dimensions: 50mm depth. 40mm square top bore tapering to a 32mm base. Extraction: 1.2mm floor thickness permits mechanical release of the tomato soil plug via bottom pressure. Drainage: Single 8mm center bore per cell. Will drain immediately onto the host surface—must be paired with an 86x253mm minimum drip pan.
Pendant Ceiling Canopy
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.
Sweeping Crane Shoe Horn
Rising from a generously cupped heel like the neck of a sweeping crane, this half-meter-long shoe horn bridges the gap between hand and floor. The elongated, curving silhouette is designed for bodies that prefer to remain upright, translating a gentle pull into a perfectly seated heel without demanding a painful forward fold. The structural arch provides rigidity along its substantial length, ending in a flared, comfortable grip. Form & Function The Reach: 500mm of unbroken length to save the lumbar spine from unnecessary contortions. The Scoop: A 60mm wide, smoothly radiused curve shaped to comfortably embrace a heel without pinching. The Roost: A 10mm hanging hole at the crest of the handle keeps it suspended and accessible on a closet hook.
Universal Dust Bag Dock Adapter
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. Design Notes Parametric setup: The code exposes variables for the dock plate footprint, suction tube diameters, and the universal bag's collar dimensions. Orientation: Built with the dock interface on one side and the bag rails on the other. You will need supports under the central tube if printed with the rails facing up. Tolerances: The default rails leave a standard 0.5mm clearance for a typical 3mm cardboard collar.
AeroFlow — Dual Fan Vent Manifold
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
Aura — Squat Vintage Lampshade
