Create a 3D printable, grid-style storage tray designed to hold small cylinders. The tray must have exactly 120 blind circular slots arranged in a precise 10x12 matrix. Each individual slot must have a precise diameter of 13 mm and a total internal depth of 12mm. The bottom surface of each slot must be flat and closed. Maintain a wall thickness of 2mm between adjacent slots. The tray should be a single, solid rectangular block

Generate a 3D model for the top cover of a handheld device enclosure. The internal cavity is 65.5mm x 30.5mm. Use a wall thickness of 1.5mm and a total internal height of 8mm.

Include the following precision cutouts on the top face:

LCD Screen Window: A centered rectangular cutout of 32mm x 38mm. The center point is (32.75mm, 15.25mm).

Navigation Buttons: Five circular holes, each 5.5mm in diameter. Place four in a D-pad cross formation: Up (12mm, 20mm), Down (12mm, 10mm), Left (7mm, 15mm), Right (17mm, 15mm). Place the fifth 'Select' button at (53mm, 15mm).

Microphone Ports: Two 1.5mm circular holes located at (5mm, 5mm) and (60mm, 5mm).

Speaker Grille: A 12mm x 12mm area at the top-right (50mm, 22mm) consisting of five 1mm wide horizontal slots spaced 1mm apart.

Mechanical Features:

Add four internal M2.5 screw bosses at the corners: (3.5mm, 3.5mm), (62mm, 3.5mm), (3.5mm, 27mm), and (62mm, 27mm).

Ensure a 2mm fillet on all exterior edges for comfort.

Generate a high-quality, 3D printable STL model of a simple rectangular ammo holder tray for 6.5 Creedmoor cartridges. Overall dimensions: 150mm length, 220mm width, 50mm height. The tray is a solid rectangular block with an array of tapered holes arranged in a tight grid of 11 rows by 16 columns (total 176 holes), centered on the top face with at least 1mm material between holes and minimum 1mm walls around the edges for structural integrity. Each hole is designed to hold a cartridge bullet-down for stability: from the top surface down, first a cylindrical section with 12mm diameter and 14mm depth (for the cartridge body); then a conical taper section with 30-degree shoulder angle (tapering inward from 12mm to 7.5mm diameter); followed by a 7.5mm diameter cylindrical section extending to the full remaining depth (about 50mm total hole depth). Ensure the model is watertight, manifold, with clean topology, no overhangs over 45 degrees, minimum wall thickness 1mm, and optimized for FDM 3
