I am looking for a performer for 3D modeling and the development of design documentation for a classic type air heating boiler fueled by wood, with a burning duration of 6-12 hours. Power output is 20 kW.Tasks: 3D model in SolidWorks (assembly + parts: casing, combustion chamber, heat exchanger, ash pan, flue gas unit) Working drawings of parts and assembly drawings Specification (BOM)Requirements: Experience in designing boilers, heat exchange equipment, or sheet metal (welded structures) Proficient in SolidWorks (Sheet Metal, Weldments) Understanding of basic thermal calculations — an advantageDeadline: 2 weeks Format: can be conveniently discussed after the responsePlease send a portfolio with examples of similar work (boilers, heat exchangers, welded metal structures).

Make technical cards for rolls, so that everyone can understand. 50-60 items. Cold, hot, and baked rolls

Development of a technical plan for sockets and switches based on the ready-made furniture drawing (Rivne / remotely). Hello! I am looking for a design engineer or technical draftsman to develop an electrical scheme for builders. What is available: An accurate drawing of the rooms with wall dimensions. Approved furniture and plumbing layout plan (where everything is placed). No 3D visualizations. What specifically needs to be done (Technical requirements): Socket and switch plan: Place points in relation to the dimensions of furniture and appliances. Specification by type (moisture protection): Clearly indicate the type of sockets for wet areas (for example, moisture-proof with grounding and IP44 covers for the bathroom). Calculation of power lines (cables): Highlight and specify power points that require a separate cable of increased cross-section (for example, for the cooktop, oven, powerful boiler) and separate lines for appliances like the extractor fan. Switch scheme: Consider convenient light control (three-way switches, linking to lighting groups). Result: A finished drawing in PDF format with accurate dimensions, clearances from walls/furniture, and technical notes for installers. Please indicate the cost of your work (for the entire project or per sq.m) and estimated completion time? 120 kV. Thank you!

I have several ready-made samples of steam fireplaces, including a model that serves as a reference for quality, design, and functionality. The task is to develop a proprietary product under our own brand based on the analysis of existing solutions. Main tasks: complete technical analysis of existing samples; disassembly of the structure and components; determination of the operating principle of all units; preparation of technical documentation; creation of a bill of materials (BOM); selection of alternative suppliers for components; cost evaluation of production; development of the concept for our own product; preparation of a plan for transitioning from prototype to mass production.
