Eldosa — Distribution Enclosure
Created today
Description
An electrical distribution and breaker box built for modular wiring. It features dedicated routing channels running alongside a raised central mounting boss, keeping cables neatly separated from the active components.
The box relies on a simple, robust knuckle hinge designed to take a piece of 1.75mm filament as the pin.
Features
- Inputs & Outputs: Three large 16mm inputs on the left flank, and five 12mm output holes on the right.
- Internal Routing: Twin divider walls keep power runs clean and separated from the main breaker rail.
- Hinge Design: Alternating 24mm knuckles on the box and lid mate tightly. Slide a bit of standard 3D printer filament through the 2.4mm bore to link them together.
- Signage: Raised "ELDOSA" lettering on the top cover.
Print notes
Print both parts flat on the bed. No supports are needed for the box's side holes if your printer handles bridging well, though you can add them if you prefer perfectly round cutouts. Ensure your bottom layer isn't heavily squished, or you may need to ream out the hinge holes with a 2mm drill bit before inserting the filament pin.

Hinged Dragon Injection Mold
Pouring liquid plastics into split molds usually ends with the halves sliding out of alignment, ruining the cast and spilling hot material everywhere. This print-in-place clamshell mold fixes that by locking the halves together with a permanent hinge and alignment pegs, ensuring a perfect seal every time you close it. The internal cavity forms a smooth, undercut-free dragon shape, fed by a top-mounted injection funnel. Air vents run across the parting line to prevent bubbles from trapping in the wings or tail. Mold Specifications Closed Dimensions: 100mm wide x 70mm tall x 30mm thick. Cavity Size: Roughly 45mm x 55mm (scales cleanly). Clearance: 0.5mm on the hinge mechanism — ensure your extrusion multiplier is tuned so the cones don't fuse. Material: Print in PETG or ABS for thermal resistance if injecting warm wax or low-temp thermoplastics; TPU works brilliantly if you need a flexible mold to aggressively demold rigid casting resins.

Channel — Micro U-Profile
A precision micro U-channel profile built to exact specifications. Designed as an inverted U-shape, it features consistent 2mm wall thickness throughout. Dimensions Width: 8 mm Total Depth: 6.5 mm (yielding a 2.5 mm internal channel) Total Height: 9.5 mm Wall Thickness: 2 mm on both verticals and the top span Print notes Prints easily in its current orientation with no supports required. A slight 0.2mm chamfer has been applied to the outer top edges to eliminate sharp corners.
Heavy-Duty Strap Tension Lock
A heavy-duty tension lock (tri-glide slider) sized perfectly for standard 50mm (2-inch) nylon webbing. This single-piece buckle uses a reinforced and raised center bar to ensure high friction, keeping straps tightly locked under load. Key Features Perfect Fit: 51mm internal width to give thick duty straps just enough clearance. Aggressive Grip: Three raised cylindrical ridges span the center bar to bite into the woven nylon and prevent slow slipping. Heavy-Duty Walls: 6mm thick external walls and a 9mm tall command bar mean this won't snap under tension. No Support Required: Prints entirely flat on the build plate.
Brutalist Saddle Bench Anchor
Rising from the workbench like a brutalist saddle, this monolithic cloven block transforms a standard 20mm dog hole into a firm cradle for unpredictable geometries. The heavy, geometric V-cut cleft is engineered to catch and stabilize rolling stock—dowels, metal pipes, or turning components—locking them dead-center against clamping pressure. By sinking a steep peg below the benchline, the fixture acts as an immovable anvil for holding cylindrical parts during routing, carving, or sanding tasks. Fixture Geometry The Cleft: A 90-degree notch spans the entire 50mm crown, dropping deep into the block to maximize surface contact on cylinders. The Root: The 30mm anchor peg is tuned to a 19.8mm diameter and features a tapered tip, ensuring a smooth plunge into 20mm bench holes while allowing just enough clearance to prevent binding. Bed Orientation: Invert the block so the flat top face sits flush against the build plate, allowing the entire model to print completely support-free.
Narrow Dyson V11 Crevice Tool
A specialized extension nozzle designed for reaching deep into narrow spaces, such as car seat gaps and tight tracks. The base features a 35.5mm inner diameter sleeve tailored to fit over a 35mm Dyson V11 wand collar, providing a secure friction fit over a 25mm depth to clear standard spring-clip catches. The main body flattens out, while the final 20mm tapers sharply into a thin slot for maximum penetration into cramped areas. Mounting interface: 35.5mm ID, 25mm deep sleeve intended for Dyson V11 mounts. Nozzle profile: Flattens along the shaft, tapering to a highly restricted slot at the tip. Target application: Automotive interior detailing and reaching confined household crevices.
