Description
A four-way distribution manifold for standard 1/2" PEX tubing, complete with a ground stake and modular caps.
This version strips out the internal metering needle on the top cap for unrestricted flow, making it a straight-through distribution hub.
Remixing: The M14 top thread is standard enough that you could easily swap the blank cap for a custom dripper, a gauge mount, or a bleed valve. The blind hole on the bottom can also be tapped deeper if you want to route water down instead.

A compact, print-in-place water manifold built for automated plant irrigation systems. It splits a single main feed into four independent channels with smooth internal transitions to minimize flow restriction. Inlet: Single center-mounted fitting sized for 8mm ID hose. Outlets: Four equally-spaced fittings sized for 5mm ID hose. Barbs: Dual retaining ridges on all connections to prevent slip-offs under pressure. Internal Channels: Fully hollowed 7mm common chamber with spherical transitions to eliminate dead zones and sharp fluid corners.
Hoses slipping off a plain tube is a guaranteed flood. This 4-way manifold uses aggressive, precisely sized barbs to bite into soft tubing, routing one 8mm inlet into four 5mm outlets. Critical Fit Inlet: 8.2mm main shaft, 10mm max OD on three barbs. Outlets: 5.2mm main shaft, 6.7mm max OD on two barbs each. Flow: Internal bores are necked down to 3mm on the branches to preserve wall strength, expanding to a 16mm central chamber. Print it base-down. The horizontal barbs are short enough to bridge without supports if your part cooling is dialled in.
A heavily reinforced Y-shaped hose connector built specifically to merge two fluid lines into one. Designed for 8mm inner-diameter flexible tubing, it uses a solid central hub rather than thin overlapping walls, ensuring the part handles pressure without snapping at the junction. The internal geometry is sculpted to maintain flow: a 6mm channel through the main body prevents a bottleneck at the merge, smoothly necking down to 5mm inside the barbs to guarantee thick, watertight perimeters where the plastic gets thinnest. A precision flat cut on the underside allows the entire assembly to drop straight onto the build plate, completely eliminating the need for support material. Remix Hooks & Constraints Hose Fit: The double barbs peak at 8.5mm OD and drop to a 7.2mm valley, grabbing 8mm ID silicone or vinyl hose tightly. Print Settings: Built for PETG or ABS. Use 4 to 5 perimeters to ensure watertightness and maximum mechanical strength against bending forces. Scaling: Scaling up works cleanly for larger hose (e.g., 125% for 10mm ID), but scaling down is not recommended as the internal channel will restrict flow and the walls may drop below the required thickness for a watertight seal.
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. Threaded joints: 21mm male thread with a matching 21.6mm female thread cut into the base, providing 0.6mm of clearance. Support-free design: Internal transitions use 45-degree tapers, eliminating the need for internal supports. Slim profile: Maintains a 25mm outer diameter with a robust 3mm wall.
M18 threaded bulkhead fitting engineered to pass an 8mm inner-diameter irrigation hose securely through a plastic tank lid. Interface: M18x2 thread with an independent hex locking nut. Sealing: Recessed O-ring groove on the interior flange face (2.5mm wide) to provide a watertight seal against the tank wall. Hose Barb: Double retaining barbs with a reinforced transition cone to handle clamping forces. Clearance: The hex nut is designed to slide freely over the 10.2mm barbs and internal threads are sized for clean printing in PETG. Both components are oriented to print flat on the bed without supports.
A modular wildlife escape ramp built to saddle the rim of a 150-gallon stock tank. Designed to hang tight against the straight section of the wall, it leaves the center of the trough wide open while providing a secure path out of the water. Features Modular Assembly: Print the sections flat and slot them together using the flush integrated joints. Safe Traction: Half-cylinder ribs spaced evenly along the ramp offer grip without sharp edges that could catch paws or hooves. Dual Path: Includes both an inner descent into the water and an optional exterior ramp leading down to the ground. Rim Saddle: The central mount is contoured to slot cleanly over a standard 40mm rolled trough rim. Dimensions Width: 150mm (approx 6 inches) Incline: 35 degrees Segment Length: 300mm per section, yielding a ~344mm vertical drop per side (well below the typical waterline).
