    I print 4–5 m cotton lengths every day with a single colour. Right now I block-print each piece by hand with wooden stamps, lifting, realigning, and stamping the fabric five times before rolling it forward. The manual cycle is accurate but far too slow, so I want to replace only the stamping phase with a faster, low-cost, semi-automatic alternative based on screen printing. Here is the workflow that must stay: I will still feed, tension, and roll the fabric manually between passes; patterns change daily, so the tooling has to let me swap a screen or frame quickly without expensive re-registration steps.

    I have a batch of precision metal parts that must be produced on a lathe to very tight tolerances. All work is on metal stock only—no wood or plastics. The tasks involve three core operations: turning multiple diameters, facing surfaces perfectly square, and cutting both internal and external threads exactly to the drawing specifications. I will provide detailed PDFs and STEP files that call out ±0.02 mm tolerances and surface-finish requirements. You will take the project from raw bar to a fully inspected, production-ready component. That means setting up the machine, choosing the right tooling and inserts, dialling in speed/feed and coolant, running in-process micrometer checks, and completing a final inspection before parts leave your shop. Consistency across the small-to-...

    I need a complete HVAC design for a retail space under 1,000 sq ft. Comfort is the priority, but indoor air quality and day-to-day energy savings must be accounted for from the first load calculation to final equipment selection. Scope • Heat-gain / heat-loss calculations sized to the exact floor area and retail usage profile. • Equipment schedule that balances temperature control, MERV-rated filtration and high SEER/EER performance. • Ductwork or mini-split layout (whichever proves most efficient) with diffuser locations that avoid dead-zones around shelving and displays. • Simple control strategy—programmable thermostat, demand-controlled ventilation or other cost-effective option you recommend. • Drawings and schedules delivered in PDF; native A...

    I need a seasoned SolidWorks expert to take a complex, multi-component mechanical part from concept to fully detailed, production-ready files. The assembly features numerous moving pieces and tight tolerance interfaces, so every part must be built parametrically, properly mated, and clearly documented. Once we kick off, I will share all functional requirements, material preferences, and critical dimensions. From there I expect you to develop the 3D parts, assemble them, verify clearances, and prepare manufacturing drawings that a machine shop can use without extra interpretation. Native SolidWorks 2021+ is preferred so I can review and make minor edits later. Deliverables: • Native .sldprt and .sldasm files, fully constrained • 2D fabrication drawings with dimensions, toleran...

    I’m ready to move from store-bought units to a purpose-built charcoal smoker that can comfortably hold three to four racks of meat. My priority is a rock-solid stainless-steel construction that maintains steady, even heat while still giving that classic charcoal flavor profile. What I need from you is a complete, fabrication-ready package—something a local metal shop (or an experienced DIY fabricator) can use without having to guess about dimensions, tolerances, or airflow. I already know the basic size I want; now I need the professional design expertise to make sure the firebox, chimney height, dampers, and insulation all work together. Key deliverables: • Fully dimensioned CAD drawings (DWG or SolidWorks preferred) • Cut/parts list specifying stainless grades, ...

    I have already modeled a sheet-metal cabinet for a parking-payment terminal nad barrier gate in SolidWorks, but as a newcomer my version looks bulky and dated. I want you to refresh the overall design with a clear emphasis on aesthetic appearance while keeping it easy to manufacture on my fiber laser and electro-hydraulic press brake. The refreshed enclosure must stay entirely sheet-metal, nest efficiently on standard 1.2 mm stainless or mild-steel, I have a series of similar kiosks and enclosures in the queue, so this first project can lead to ongoing work if we hit the right balance between looks and manufacturability.
