Create a high-quality isometric 3D render of a desktop pen holder with an integrated phone stand, designed for 3D printing. The pen holder is cylindrical, made of smooth matte plastic, with: • Height: 100 mm • Outer diameter: 75 mm • Wall thickness: 3.5 mm • Flat, stable base On one side, include a slanted phone slot: • Slot width 16–18 mm • Slot depth 18–20 mm • Slot height about 60 mm • Slot inclined at 65 degrees • Smooth filleted edges around the slot Emboss the name “PRATYUSH” in raised text (2 mm depth) on the front curved surface, clearly visible in isometric view. The model must be a single solid body, with rounded fillets on all edges, designed for FDM 3D printing (PLA/ABS). Render the model in an attractive blue color, with soft studio lighting, white background, and clean engineering-style presentation. Show the product in isometric perspective, emphasizing functionality, simplicity, and aesthetic balance. No extra decorations, no patterns, no logos other than the embossed name.

A smooth metal ring for 3D printing with an 18 mm inner diameter. The ring features a smooth round top with an embossed "M" logo and no surrounding symbols. The band is smooth and of uniform thickness around the entire perimeter. As in the example photo, the back should have an engraving reading "Mellstroy Game." Small, evenly spaced casino-themed engravings on both sides of the band include dice, hearts, spades, clubs, clovers, sevens, and stars. These are slightly smaller and simple enough for 3D printing. The surface should be polished dark metal with subtle purple-gold highlights and crisp geometry suitable for high-quality 3D printing.

A sleek metallic 3D-printable ring with an inner diameter of 18 mm (for a sporty male, 15–16 years old). The ring has a clean circular top with a raised bold “M” logo — no symbols around it. The band is smooth and even in thickness all around. Around half of the outer band, the engraving reads “Mellstroy Game”. On both sides of the band, there are small, evenly spaced casino-themed engravings — dice, hearts, spades, clubs, clovers, sevens, and stars — slightly smaller and simple enough for 3D printing. The surface should be polished dark metal with subtle purple-gold reflections and clean geometry suitable for high-quality 3D printing.

A 3D printable air vent manifold for FDM printing. The model consists of: - A flat rectangular base plate, 150 mm long, 25 mm wide and 6 mm thick, made to be screwed onto a surface. The base has 4 countersunk mounting holes (4.5 mm diameter, suitable for M4 screws) . one on each corner. - Five adjustable air outlet nozzles evenly spaced along the 150 mm length, connected to the base via a functional ball-and-socket joint. - Each nozzle is a short cylindrical duct, 28 mm long, 22 mm outer diameter, 18 mm inner diameter, with rounded edges for smooth airflow. - optimized for 3D printing

The ball joint is designed to be printed in place with minimal clearance (0.3 mm) so it moves freely after printing but stays secure. - solid walls with 2 mm minimum wall thickness, no thin features, optimized for FDM 3D printing
