Create a compact 3D-printable ampoule holder with 6 slots: 4 slots (15mm diameter, 75mm length), 1 slot (12mm x 53mm), 1 slot (10mm x 46mm). Arrange in 2 rows with 2–3mm wall thickness.

Design as 2 parts: bottom body + top lid. Include an integrated hinge (print-in-place or pin style) for smooth opening.

Add 2 aligned magnet holes (≈5mm diameter, 2mm depth) for secure closure.

Each slot must have a small side cutout for easy ampoule removal. Add tolerance (0.3–0.5mm).

Optimize for FDM 3D printing (PLA): no supports, flat base, rounded edges, compact and ergonomic design. Minimalist medical/tool style.

3D model: Extra-long matte lime-yellow rectangular tray. Estimated dimensions: 170mm (L) x 70mm (W) x 12mm (D). Features a deep, precise central well. Crucially, each of the two long interior side walls contains exactly 30 identical, evenly spaced, 3mm diameter cylindrical pivot-pin slots, cut cleanly into the vertical faces for a dense, dense array (60 total slots, arranged in opposing pairs). The pattern covers nearly the entire length, maintaining equal and small pitch. Two raised guide tabs are present on the top surface of the outer long walls. Clean isometric perspective view showing the extreme length and the repeating slot pattern. Rendered on a neutral grey studio background.

Geometry & Dimensions:

Primary Shape: A perfect solid cylinder with a diameter-to-height ratio of approximately 1.2:1 (e.g., 12mm diameter, 10mm height).

Top Surface: Completely flat circular face. The top outer edge must have a subtle 0.5mm radius fillet (bevel) for a smooth finish.

Bottom Face: Recessed and hollowed out, featuring a central mounting boss.

Internal Mounting Socket (Crucial):

Type: "D-shaped" blind bore (D-shaft socket).

Details: A central circular hole with one flat vertical side to prevent rotation. The hole must not penetrate the top surface (stop 1.5mm before the top).

Support Structure: 4 thin radial reinforcement ribs connecting the central D-bore housing to the outer cylinder wall, positioned at 90-degree intervals.

Material & Texture:

Material: Matte black injection-molded plastic.

Surface: Non-reflective, slight micro-texture, no parting lines or logos.

Color: Hex #1A1A1A (Deep Matte Black).

Output Requirements:

"Design a small cylindrical cap to plug a twelve millimeter diameter hole. The cap should be three millimeters tall to match the lid depth, with a very thin top wall — make it as thin as possible while keeping it printable, around zero point five to one millimeter thick. The bottom should have a slight interference fit or small lip so it snaps securely into the hole. On the very top surface, emboss a bold capital letter W, about eight millimeters tall. Keep the whole thing simple, smooth, and easy to print."

Create a 3D printable top shell enclosure:

OVERALL: 60mm wide × 40mm deep × 20mm tall. Wall thickness 1.8mm.
Smooth matte exterior. 0.5mm fillet on all outer vertical corners.
No overhangs over 45°. FDM printable without supports.

FRONT FACE:
- Display cutout: 38mm wide × 27mm tall, centred, 1mm recessed
to seat TFT PCB. 1mm chamfer around inner edge.

TOP FACE:
- Microphone hole: 4mm diameter, 12mm from left, 8mm from front.
- Four M2 screw boss holes (3mm OD, 2mm deep) at inner corners.

LEFT SIDE:
- Speaker grille: five slots, each 2mm wide × 10mm tall,
evenly spaced and centred vertically.

REAR FACE:
- Two 4mm diameter cable pass-through holes, 10mm from each
side edge, 8mm from top.

BOTTOM RIM:
- Four snap-fit tabs (4mm wide × 3mm tall × 1.5mm thick)
protruding downward — two on front wall, two on rear, evenly spaced.
- Four alignment pin holes (2mm dia × 2mm deep) at inner corners.

Generate a 12mm diameter mechanical wheel designed for a guitar.
The wheel is 2mm thick with a 2.0mm "D-shaped" center hole.

CRITICAL ALIGNMENT FIX:
The 16 picking teeth should not point straight out from the edge. Instead, they must be "Side-Mounted" or "Offset." Each tooth should be angled slightly outward toward the side of the wheel so they can make contact with a string running alongside the wheel's face.

PICK SHAPE:
Instead of simple triangles, shape each of the 16 teeth to look like a "Miniature Standard Guitar Pick" (teardrop shape). The picks should have a wide base where they attach to the wheel and a smooth, pointed tip where they hit the string.

VISUAL STYLE:
The wheel should look like a "Matías Krantz" invention—industrial, rugged, and aggressive.
Use a "Turbine" or "Fan blade" spoke design for the inner body.
The material should look like Matte Black Carbon Fiber.

FUNCTION:
This is a high-speed "Shred-Wheel." The offset picks must be positioned specifically to "slap" a guitar string as
