I’ve already sketched and modelled a sleek, pen-sized instrument that fuses four everyday essentials for medical-device reps: a fine-tip pen, a permanent marker, a rechargeable laser pointer, and a concealed, auto-retracting ceramic blade for opening cartons. Now I need to see it come to life in the form of one or two fully working prototypes that prove every feature actually functions. Functionality and quality are my top priorities. The prototypes have to write cleanly, shine a steady laser, and retract the blade the instant pressure is released. To make that viable all day, battery life and a convenient USB-C (or similarly compact) charging solution are non-negotiable. Safety is equally critical: the laser must include recessed button for activation, and the ceramic blade mechani...

I need a clear and professionally drafted electrical single-line diagram based on the electrical load list along with safety features that shows how power will be distributed throughout a small-scale gas plant facility. The drawing must follow the NEC (National Electrical Code) so that it can be submitted directly to our local authority for review and later handed to the construction team without additional rework. Scope of work – Capture the complete power distribution path from the utility tie-in through to all downstream loads, including metering points and breaker information. – Use standard electrical symbology and layer naming so I can easily integrate the file into our master AutoCAD set. A clean PDF export is also required for circulation.

I need an engineer-designer who can take my concept for a medical-grade breath-sampling mouthpiece and turn it into a production-ready part. The core requirement is a passive, purely mechanical flow restrictor that caps expiratory flow at roughly 100 mL/s so the downstream analyser always receives a stable, repeatable sample. Material and user experience The body should be 3d printed or injection - mouldable plastic; no mixed elastomers unless you recommend a soft over-mould solely for the lip interface. Above all, the final geometry must feel natural between the lips—comfort outweighs cleaning convenience or extreme durability in this application. Performance specifics • Flow restriction: target 100 mL/s ±10 %, unpowered, with typical adult exhalation pressures. ...

I’m ready to turn my concept for a sub-5-metre salt-water fishing boat into a fully engineered reality and need an experienced naval architect to take the lead. The goal is a sturdy, trailer-able craft that comfortably carries two anglers and their gear while handling choppy coastal conditions with confidence. You’ll start from my rough sketches and performance targets, then develop the complete design package—hull lines, structural scantlings, weight estimates and hydrostatic data—working to ABYC or ISO small-craft standards. I’m open to aluminium or fibreglass construction; your analysis and recommendations will guide the final choice. CAD expertise with tools such as Rhino + Orca3D, Maxsurf, SolidWorks or similar is essential, along with a proven track re...

I have a single hand‑drawn schematic of custom distillation equipment that needs to be converted into a clean, accurate, professional mechanical drawing suitable for direct submission to a fabricator. All dimensions on the sketch have already been verified. But there might be questions that the Freelancer may have in order to do this properly. Your task is not to redesign, interpret, or modify the geometry — only to faithfully transfer the drawing into proper drafting format. I also have multiple photos of the real equipment, and additional measurements can be taken on site upon request. If you need a specific angle, dimension, or detail to ensure accuracy, I can provide it quickly.

I need support preparing a clean Bill of Materials and producing matching 2-D mechanical drawings for a small machine sub-assembly that is already roughed-out in sketches. The goal is to leave me with documentation that a fabricator can pick up tomorrow without any back-and-forth. Scope • Translate my hand sketches (PDFs and photos) into professional 2-D mechanical drawings ready for DWG/DXF and PDF export. • Build a structured Bill of Materials that mirrors every item shown on the drawings, including part numbers, quantities, basic descriptions and material call-outs. Preferred workflow I normally review work in AutoCAD or SolidWorks, so native files in either platform plus PDFs work best. A short online walkthrough after the first draft will let us close any gaps before...

I need a precise mechanical engineering drawing. The drawing should be highly detailed, including measurements and annotations. Ideal candidates should have: - Proficiency in mechanical drawing software (AutoCAD, SolidWorks, etc.) - Experience in creating detailed engineering drawings - Strong attention to detail and accuracy

I have a set of electrical schematics that now need to be turned into production-ready drawings. The job calls for both 2D drafting and 3D modeling in AutoCAD: flat wiring diagrams that clearly label every symbol, conduit run, and termination, plus a companion 3D layout that shows how the components sit in space for enclosure and cable-routing checks. The level of finish I’m after is moderate—clean line weights, organised layers, accurate dimensions and call-outs, but not the ultra-dense fabrication detail you might see on shop drawings. Think installation-ready rather than photorealistic. To make it easy for us to iterate, I’ll provide the rough hand sketches, device lists, and reference photos. You return: • Editable DWG files for both the 2D schematic and ...

I have a complete set of architectural and MEP drawings for a new Physical Therapy / GYM facility in West Columbia, Texas and I need them professionally sealed by a Texas-licensed PE.

I’m developing a new HVAC unit and need an experienced mechanical engineer to take it from concept to production-ready design. The engagement centers on full product design, with particular attention to thermal performance inside an HVAC system where end-user comfort is the primary metric of success. You’ll translate my functional requirements into detailed 3D models, run the necessary thermal simulations to verify airflow, temperature distribution, and noise levels, then iterate until we meet comfort targets. Expect to work in common toolchains such as SolidWorks (or similar CAD) and a CFD package like ANSYS CFX/Fluent for the thermal side; if you prefer an equivalent platform, that’s fine as long as the results are exportable. Deliverables • Parametric CAD model ...
