Tank Tap Bulkhead Fitting 1 1/2" BSP
Created today
Description
A through-wall bulkhead fitting in the spirit of a classic water butt tank connector: a broad round flange sits against the tank wall, a long threaded barrel passes through, and a matching lock nut clamps it from the other side.
- 72 mm flange with a shallow gasket seat for a flat washer or O-ring
- 1 1/2" BSP-style male thread (47.8 mm major diameter, 11 TPI), 40 mm long
- 38 mm through bore
- Separate lock nut, printed alongside
Design notes:
- The thread is a generic approximation of the Whitworth form, so test-fit against your mating part.
- Cut the tank hole to suit the thread, and use a rubber gasket against the flange.
- Print the flange face-down; PETG is a sensible choice for water contact.

280mm Irrigation Controller Enclosure
A rigid 280 × 200 × 90 mm printed enclosure designed specifically for an ESP32-based multi-zone plant irrigation controller. The layout divides the internal volume into three distinct areas: high-current power distribution on the left, six MOSFET drivers in the center, and the low-voltage microcontroller logic on the right. An extra-wide central cable channel runs between the two rows of MOSFETs, and all high-traffic access areas—like screw terminals and adjustment dials—have generous working clearances. The outer walls feature deep U-slots for cables, cut from the top edge so the main flat lid traps them cleanly in place without relying on separate cable glands. Internal Layout details Zone A (Power): Mounts for a 56×35 mm DC-DC buck converter, a friction-fit bracket stack for four WAGO 221-415 lever connectors, and a C-clip for an inline 5A barrel fuse. Zone B (Switching): Two rows of custom mounts for six 35×32 mm MOSFET boards. Each uses exactly two diagonal standoffs to leave maximum free space around the terminals. Zone C (Control): Stand-offs for an ESP32 NodeMCU, with a dedicated USB-C opening aligned in the external right-hand wall. Structure: Embossed floor labels mark all hookup zones. Cable tie bridges are scattered throughout the base for organization, and vertical ventilation slots flank the rear and sides. Uses four M3 screws driven directly into heavy internal corner bosses to seal the lid.
Reinforced 8mm Irrigation Y-Splitter
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.
120mm Self-Watering Planter
A 120mm diameter by 120mm tall self-watering planter designed to keep moisture-sensitive plants like basil alive. The bottom 30mm acts as a dedicated water reservoir, separated from the soil by a perforated platform and a central wicking column. A built-in fill tube routes water directly to the base, while a side window at the 15mm mark provides a visual water level check and acts as a hard overflow drain to prevent drowning the roots. Starting Points for Remixing Scale and Proportions: Overall footprint is 120x120mm. Stretching the Z-axis is straightforward, but requires manually offsetting the 30mm platform and 15mm overflow window to maintain the reservoir geometry. Platform Flow: The internal drainage perforations are currently set to 3.5mm. Widen these for coarse chunky soil mixes, or tighten the grid spacing for more aggressive root aeration. Wicking Column: The central 40mm wicking cone drops to the base with 10mm side slits. Depending on the soil's capillary action, adjusting the slit height changes how quickly the topsoil hydrates. Print Pairings: Prints as one solid piece without supports. Best paired with PETG for long-term water tightness and UV resistance if placed on a windowsill.
Straight Cylindrical Pipe
A straight cylindrical pipe with a uniform wall thickness, designed for fluid transfer, structure, or sleeving. Inner Diameter: 60 mm Outer Diameter: 64 mm Wall Thickness: 2 mm Overall Length: 60 mm
Twisted Planter With Name Plaque
A 100mm base hexagonal planter with a deep twist and a prominent front plaque. The planter features a solid 5mm-thick wall that precisely tracks the exterior twist, terminating in a flared rim. It includes a central 8mm drainage hole alongside five 10mm perimeter holes. A pill-shaped plaque sits seamlessly flush on the front face, equipped with extruded placeholder text ("NAME") that will export as part of the geometry—ideal for setting up multicolour text in your slicer. Check your drip tray to ensure the 100mm base clears the lip.
