Aquaponic Burp Pump Valve 45
Created 6 days ago
Description
What it's for
A custom inline burp pump valve designed for aquaponic systems. It features a print-in-place marble that acts as a one-way check valve, allowing air to displace water out the 90-degree discharge elbow.
Dimensions
- Main Body: 2-inch diameter by 4-inch length chamber.
- Discharge: 2-inch diameter extension turning 90 degrees.
- Air Intake: 1-inch diameter side port.
Print notes
- The model is currently sliced open for visual inspection — it needs to be closed before printing.
- Prints vertically on its base to ensure the internal marble forms correctly without fusing to the seat.
- Normal supports are required for the protruding air intake and top elbow.

Two-Speed Constant Mesh Gearbox
A build-it-yourself, chunky two-speed constant-mesh transmission designed for clear mechanical demonstration. All gears and shafts are laid out flat for straightforward printing. Design Features Two-Speed Setup: Includes a 15-tooth and 25-tooth spur gear arrangement. Constant Mesh: The gears are always engaged. A sliding dog clutch (the purple slider) locks the freely spinning gears to the output shaft to change the ratio. Assembly: Parts drop onto the base frame's posts. The high gear goes on the top of the output shaft (pocket facing down), the low gear goes on the bottom (pocket facing up), and the slider sits in between them on the hex shaft.
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.
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.
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.
