Description
A friction-fit cap designed for the Octo Reef Classic 110-S skimmer nozzle. It features a hexagonal mesh face to maintain water flow while keeping snails out of the inlet, and solid walls to grip the fitting securely.
The model is oriented to print upside down with the mesh resting on the bed, requiring zero supports. An interior chamfer on the open end helps it slide smoothly onto the nozzle. PETG is recommended for longevity in aquarium environments.

A stylized, single-piece model of the classic T3 Transporter double cab (Doka). It captures the signature wedge front, the shortened rear bed, and the boxy utility stance. The geometry is built specifically to sit directly on the build plate. The wheels share a flat contact patch at ground level, and the window angles act as self-supporting bridges, making it a reliable print-in-place model. Integrated base: Flat-bottomed wheels keep it stable during printing. Recessed trim: Windows and grill are built as internal blocks to give depth to the side panels. Drop-bed: The rear bed is recessed 5mm behind the cabin to mimic the real utility platform.

A robust, print-in-place mount for securing a 25x35mm front-facing bike reflector to a 12.5mm handlebar. Designed for maximum structural integrity, the mount prints entirely on its side. This orientation aligns the extrusion paths parallel to the flexing motion of the C-clamp, ensuring it can safely snap over the bar without delaminating. The clamp itself is shifted flush with the bottom edge of the mounting plate, allowing the entire assembly to sit perfectly flat on the print bed without requiring supports. Design Notes Glued Mount: The front plate features intentionally sharp 90-degree edges to perfectly frame the reflector while providing a flawless adhesion surface. All other exterior edges are softened. Hardware: The clamping mechanism accepts a standard M4x15mm screw and hex nut. Orientation: Prints as provided. The hex nut recess is oriented to bridge cleanly across the top flat.
A sturdy, support-free front reflector mount designed for an 11mm handlebar. The clamp prints vertically, keeping the layer lines parallel to the main body to allow the rear hinge to flex open without snapping during installation. Mounting: Friction fit for 11mm bars, secured with a 15mm M4 bolt Interface: Flat 25x35mm front plate for gluing a standard reflector Durability: The screw tabs are fused directly into the clamp body to prevent stress fractures Hardware: Recessed hex trap for a standard M4 nut allows one-tool tightening

A heavy-duty 10-inch subwoofer grill featuring six interwoven 1/2-inch round bars. The bars rise into a central dome for maximum excursion clearance, with the outer bars plunging smoothly along a spherical radius to anchor seamlessly into the mounting ring. Clearance: High-arched dome design to prevent cone slap on high-excursion 10-inch drivers like Kickers. Mounting: Standard 8-hole pattern on a 246mm (9-11/16") bolt circle. Hardware: Counterbored mounting holes accept standard socket-head cap screws flush with the face. Printability: Modelled completely face-down so the intricate bar crossings print flat against the glass with zero supports required.

Standard bell nozzles are a rigid compromise—they only hit peak efficiency at one specific altitude, meaning they waste fuel everywhere else. The aerospike solves this by turning the engine inside out. The exhaust plume expands against the central spike on the inside and the atmosphere itself on the outside, automatically adjusting its own expansion ratio as pressure drops. This is a functional model of an annular aerospike, heavily optimized for FDM printing. It uses a mathematically derived 1.5-power-law curve for the central plug, which efficiently redirects the radial flow from the combustion chamber into pure axial thrust. Engine Specs Throat Gap: 2 mm annular clearance around the base of the spike. Truncation: The spike is cut at 80% of its theoretical ideal length. This flat base eliminates dead weight while retaining roughly 99% of the full-spike efficiency, thanks to base-pressure recirculation. Support Structure: 6 internal struts carry the outer cowl load across the combustion chamber. Printability: Fully print-in-place with no supports required. The base sits flat, and the steepest overhang in the combustion section is well within safe limits.
A 70mm floating feeding ring designed to corral flake food and keep it clear of the filter intake. The unit anchors to the tank glass via a single suction cup mount and features a fully enclosed hollow 12mm rim to maintain permanent buoyancy. Fitment details: Mounting standard: Mates with a standard 20mm aquarium suction cup. Neck clearance: 6.5mm center bore with a 2.5mm side entry slit. Slip the rubber stem through the channel rather than forcing the nub through a rigid hole. Incompatibilities: Will not fit oversized heater-mount cups or miniature 4mm airline tubing clips. Verify the neck diameter of the suction cup before printing.
