Assembly Principle: Completely weld-free, exclusively using bolted connections (“NO-WELD BOLTED CONSTRUCTION”). The structure is modular (Flat-Pack) to minimize logistics costs and facilitate self-assembly by the customer. 1. TECHNICAL REQUIREMENTS AND AESTHETICS • Requirement for the developer: The product must be designed to have a flawless, presentable commercial appearance for export to the EU market. • Intuitive assembly: The design should allow for the simplest assembly possible, enabling the customer to assemble the box independently without special tools. • Frame material: Stainless steel AISI 304 (matte), sheet thickness — 1 mm. • Construction: Corner system with flanging for rigidity and safety. Stacking (nesting) during transportation. • Wall filling (sandwich): PIR board (30 mm) with a tolerance of ±4 mm. The groove design should compensate for this tolerance, eliminating gaps. • Wall cladding: PIR board is covered on both sides with smooth stainless steel sheets of 0.5–0.6 mm. • Assembly: Strictly with bolts (stainless steel A2/A4). Minimum number of bolted connections inside the working area for ease of cleaning and disinfection. • Feet: Height 30 mm, integrated into the lower binding contour. 2. DOOR CONSTRUCTION AND LOCKING • Sealing: Rubber seal around the entire perimeter of the reveal and a stop (false bar) for 100% elimination of gaps. • Hinges: Seat design that eliminates play (bolts serve only the function of clamping). • Locking: Mechanical latch lock “finger in hole”. • Door configuration: Doors spanning the full width and height of the facade, divided horizontally into two independent sections: upper and lower. ◦ Lower section: blind. ◦ Upper section: has a viewing window. ◦ Operating principle: The lower section opens first and, when closing, tightly presses against the upper section. • Viewing window (Product No. 1): Located in the upper section. Double-sided, with an air layer. Clamping strips for securing any transparent material (glass, plastic, or film) with a thickness of from 2 to 5 mm. 3. VENTILATION SYSTEMS (Identical for both products) • Protection: Mesh (stainless steel, wire 0.5 mm, cell 0.8 mm). Installation — through clamping frames with bolts (without drilling the mesh). • Upper exhaust (120 cooler): Cutout 200x200 mm in the roof, cooler installation through a flange with M4 thread. Under the cooler (above the mesh) — adjustable damper (shutter). • Lower intake: Two openings (left and right), raised 100 mm from the floor. Area of each — 300 cm². Both intakes have adjustable dampers (shutters). 4. PRODUCT SPECIFICATION • PRODUCT No. 1 (Vertical 600x600x1200 mm): Two-section doors (lower blind, upper with window). Equipment: lamp mounts, cable pass-throughs, mounts for IR film (on the wall), curtains for mesh suspension, strip for the shield from the end. • PRODUCT No. 2 (Horizontal cabinet 600x600x600 mm): Single-section doors without glazing. Equipment: lamp mounts, cable pass-throughs, mounts for IR film (on the wall), stainless steel guides for shelves, strip for the shield from the end. 5. WHAT IS REQUIRED TO BE DELIVERED: 1. 3D assembly: STEP / SolidWorks formats, with the ability to freely disassemble the model. 2. Drawings: Detailed drawings of assembly nodes. 3. Unfoldings: DXF format (considering the K-factor of bending). 4. Specification table (BOM): All stainless steel fasteners.

A gerber file is required to order a board based on the description; there is no schematic, part of the schematic (the PWM) will be drawn by hand. The set is very simple: a power stabilizer based on the ATmega 328, a 1602 display, and three buttons with a couple of small connectors.

Greetings. Development of a premium 3D model of a wooden memorial product for CNC production Project description A custom design of a premium wooden memorial product needs to be developed for further manufacturing on a 5-axis CNC. The project should not resemble classic memorial products. The main idea is a modern minimalist design. The product should look like a solid sculpture without wide frames and unnecessary decorative elements. Tasks Create a high-quality 3D model. Ensure the possibility of production on a 5-axis CNC. Design the body and lid. Consider a hidden seam line. Include hidden hinges and locks. Create an internal cavity according to standard internal dimensions. Execute the model with correct slopes and radii for wood processing. Style Minimalism. Premium design. Maximally smooth shapes. No sharp corners. No wide frames. Solid streamlined surface. Material Main material: oak; ash; walnut. Wall thickness should be suitable for manufacturing from solid or laminated wood. Result The following should be provided: STEP; STL; IGES (if possible); source CAD file; high-quality renders; drawings with main dimensions. Desired skills of the performer SolidWorks; Fusion 360; Rhino; Autodesk Inventor; Fusion CAM; experience in modeling wooden products; understanding of model preparation for CNC. Important A performer with experience in creating premium-class products and industrial design is needed. Ready to sign an NDA (non-disclosure agreement) before providing detailed technical specifications and references. Having a portfolio with complex organic or industrial forms will be an advantage.

Good day. It is necessary to develop a drawing of the product for further cutting on a CNC machine in AutoCAD. Create the drawing in AutoCAD. Prepare the file in a format suitable for CNC cutting (DXF/DWG). All dimensions must correspond to the provided parameters. Be sure to consider the cutting thickness when constructing the drawing. The contours must be closed and free of overlaps, duplicate lines, and unnecessary elements.
