FlowLink — Threaded Extension Pipe
Created 2 days ago
Description
A fully 3D-printable, 12-inch extension pipe designed for infinite stacking. The standard slip-fit ends have been replaced with integrated 3mm-pitch metric threads, allowing multiple segments to be screwed together securely without glue.
Features
- Threaded joints: 21mm male thread with a matching 21.6mm female thread cut into the base, providing 0.6mm of clearance for smooth tightening right off the printer.
- Support-free design: The internal transitions use 45-degree tapers, meaning no internal supports are required.
- Slim profile: Maintains a 25mm outer diameter with a robust 3mm wall, tapering internally only where necessary to support the threaded sections.
Print notes
Print this standing upright. Given the tall, narrow footprint, a wide brim is absolutely mandatory to prevent bed adhesion failure when the printer reaches the top threads.

Industrial Pipe and Fittings
A modular set of pipe fittings featuring a 10-inch straight rod, a perpendicular tee joint, and a straight coupling. Each piece is built around a standard 3/4-inch core diameter with robust 4mm walls to withstand practical shop use. 10-Inch Rod: Basic structural member, printed flat for optimal layer strength. Tee Joint: Three-way connector with matching bore. Straight Coupling: 60mm sleeve for joining lengths end-to-end.
Threaded Irrigation Hose Adapter
What it's for A female-to-female adapter designed to link a stackable irrigation pipe to a standard garden hose. One side features a standard 3/4"-11.5 GHT garden hose thread, while the other side is threaded to screw directly onto the pipe's male fitting. Dimensions Overall length: 38 mm Hex body: 42 mm (circumscribed) for easy hand or wrench tightening Bore: 19 mm straight through to match the pipe's internal diameter and eliminate flow restriction Design notes The internal bore transitions smoothly into flat seats on both ends, allowing standard hose washers or O-rings to seal perfectly against the fitting. The thick hexagonal walls withstand outdoor water pressure without flexing.
63×88mm Magical Deck Tray
A compact, single-piece card tray built around standard 63×88mm card stock and their protective sleeves. The front block holds five cards fanned out at a backward angle, letting you read a full hand while leaving them hands-free. A fused deck pocket directly behind it keeps the draw stack squared up. I’ve debossed a familiar three-circle mouse silhouette into the outer walls and dropped a wizard’s wand across the top rim. Fitment Deck pocket inside dimensions: 65×92mm — accommodating up to a standard 63×90mm sleeve with 1mm of clearance. Front slot: Single continuous 160mm trench pitched back 15 degrees. Captures the bottom quarter of standard cards to stop them tipping out. Print specs: Solid unibody design. All cutouts and debossing are kept shallow (1.5–2mm) so they print cleanly on an FDM bed with zero supports required.
Packout M18 Router Insert
What it's for A custom drop-in tray engineered to convert a half-section of a Standard Milwaukee Packout Organizer into a dedicated M18 router station. It features a contoured cradle for the router body with its battery attached, a wide pocket for the base plate, a large accessory bay for the edge guide and wrench, and a 12-slot storage grid for 1/4-inch shank router bits. Scalloped finger pulls make it easy to lift the router out. Dimensions Footprint: 280 mm × 200 mm Height: 60 mm Bit Storage: 12 holes, 7.2 mm diameter (for easy clearance of standard 1/4" shanks) Print notes Given the large 280 mm length, this will require a reasonably large print bed. A robust infill (15–20% gyroid) is recommended to support the weight of the tool. The design rests entirely flat on the build plate and requires no supports.
Stud-Saddle Drop Shelf
A heavy-duty drop shelf designed to wrap a standard 2x4 wall stud. The main bed splits into two pieces for easy printing on a standard bed, locking together with precision alignment dowels. A central support leg drops down directly into a face-mounted stud bracket to hold heavy loads flat. No-Support Printing: The main plates are oriented perfectly flat off the bed. Locked-In Support: The drop leg features a tubular bottom that seats perfectly into a cupped bottom bracket, preventing lateral slip. Hardware Needed: A few 6mm rod pins for the hinges, and standard countersunk wood screws for the brackets.
Machined-Style NPT Blow Gun Nozzle v4
An air compressor adapter designed to interface a 1/4" NPT blow gun with a precise 3mm outer-diameter nozzle. The part features a clean, support-free geometry that steps inward as it prints, transitioning smoothly from a 14mm hex base up through the threads, capping off with a reinforced 1mm fillet at the base of the delicate tip. Print and Application Notes Print Orientation: Prints exactly as oriented (hex base flat on the bed). No supports are required for the threads, ceiling, or nozzle. Sealing: The threads are rendered straight rather than tapered—wrap with a couple of layers of PTFE thread tape to ensure a tight pneumatic seal when threading into the metal gun. Material: PETG or ABS is highly recommended over PLA to handle the pressure spikes and avoid brittleness at the tiny 1mm bore tip.
