A single watertight 3D model of a black opaque rectangular enclosure for a non-invasive hemoglobin sensor prototype. The enclosure is a hollow box with no bottom face, designed to cover a standard half-size breadboard. Internal cavity dimensions: 58mm wide, 86mm long, 25mm high (to clear components). All walls are 3mm thick solid black plastic, making outer dimensions 64mm wide, 92mm long, 28mm tall. The bottom is completely open with a flat rim. The top face is flat and has a circular hole of 18mm diameter, centered exactly on the top face (center at 32mm from left, 46mm from front). From this hole, a cylindrical tube extends 10mm downward into the interior cavity; tube inner diameter 18mm, wall thickness 2mm, acting as a light baffle and finger guide. No other holes, gaps, or seams – the model is perfectly light-tight. Add 2mm radius fillets on all interior vertical edges where walls meet the ceiling for print strength. The entire model is a single solid mesh, perfectly watertight, o

Design a precise mechanical fixture for EDM wire cutting of a small cylindrical tube. The tube has an outer diameter of 5 mm and an inner diameter of 1 mm.

The fixture must securely hold the tube and allow accurate indexing for machining four flat surfaces (facets) around the circumference. Each facet should be rotated exactly 90 degrees relative to the previous one, resulting in four evenly spaced cuts.

Key requirements:

High-precision clamping system suitable for delicate, small-diameter tubing
Accurate 90-degree indexing mechanism (manual or integrated rotary indexing feature)
Stability during EDM wire cutting to prevent vibration or deformation
Accessibility for EDM wire path without obstruction
Compact and manufacturable design
Material suitable for EDM environment (e.g., non-corrosive, rigid metal)

Optional features:

Alignment guides for repeatability
Fine adjustment mechanism for centering the tube
Markings or detents for indexing positions

The output should be a detailed

Create a low-poly 3D model of a children's plastic crawl tunnel for a playground.

The tunnel must be a straight cylindrical tube (no curves), composed of simple modular segments aligned in a straight line. Each segment should have smooth rounded edges and be made of glossy colorful plastic (bright yellow, red, blue, and green).

Include evenly spaced circular holes/windows on the sides of the tube. The entrance should be slightly stylized and playful, but simple (no complex character faces).

Style requirements:

* Low-poly, optimized for real-time game engines (Roblox-ready)
* Minimal polygon count (very lightweight geometry)
* Clean topology, no unnecessary subdivisions
* Avoid small details that increase polycount

Structure:

* The tunnel should be a single clean model OR separated into simple modular segments
* Keep shapes simple (mostly cylinders and basic forms)

Materials:

* Simple plastic material, smooth and slightly reflective
* Solid colors, no complex textures
