Machined-Style NPT Blow Gun Nozzle v4
Created yesterday
Description
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.

1/4" NPT Golf Grip Air Adapter v2
Adapter to mate a 1/4" NPT air compressor blow gun directly to a golf club grip vent hole. Uses a 16mm hex drive for tightening. Fitment Notes Mating Surface: 1/4" NPT female blow gun ports. The model uses a straight 18 TPI thread (13.5mm OD) that relies on Teflon tape to seal against the tapered female bore. Output: 3mm OD nipple, 4mm long. Backed by a 3mm conical shoulder to prevent snapping under pressure. Bore: 1mm continuous air channel. Check this after printing — a 1mm FDM hole will likely need clearing with a wire or a 1mm drill bit before it flows air properly.
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.
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.
Knurled Tripod Thread Adapter
A threaded step adapter for mounting 3/8-16 photography and audio equipment to standard 1/4-20 tripod studs. The flanged base features a deeply scalloped outer diameter to allow firm, tool-free tightening. Specifications: Base Thread: 1/4-20 UNC (female) Top Thread: 3/8-16 UNC (male) Grip Style: Scalloped profile Tolerances: Thread profiles offset for FDM printability
Wall Mount Screwdriver Storage Rack

This wall-mounted screwdriver rack keeps six tools organized, visible, and instantly accessible right above the workspace. Designed with graduated hole sizes to accommodate everything from heavy stubby drivers down to precision tools, with front drop-in slots for smaller drivers. The back features integrated keyhole slots for clean, flush mounting onto shop walls or pegboards using standard pan-head screws. Specifications & Print Settings Overall Dimensions: 210 mm wide × 50 mm deep × 35 mm high Tool Hole Diameters: 11 mm, 10 mm, 9 mm, 8 mm, 7 mm, and 6 mm Mounting Interface: Dual keyhole slots spaced 140 mm apart (fits #8 / M4 pan-head screws) Orientation: Prints flat on its base without supports
90° Bevel Gearbox Assembly
A fully functional 90-degree bevel gearbox connecting an 8mm hex shaft to a 5mm hex shaft. The robust L-shaped housing is split cleanly down the center for easy, support-free printing and simple assembly. Specifications Transmission: 1:1 ratio bevel gears (16 teeth, 90-degree mesh). Input/Output: Built-in 8mm and 5mm hex bores, oversized by 0.2mm to accommodate standard FDM tolerances. Mounting Interfaces: Four 4.3mm clearance holes on each face flange, arranged in a 25mm square pattern. Assembly: The housing halves are clamped together automatically when bolted to a surface using the face flanges; an extra M3 hole in the rear corner provides optional tightening. All pieces print flat without supports.
