** Overview **
We need an experienced 3D/CAD designer to design an air shroud (air duct/baffle) to be 3D printed and installed in our custom server. We run a passive Dynatron heatsink, and the shroud's job is to close the gap between the chassis fans and the heatsink so airflow is forced through the heatsink fins rather than leaking around them. We'll provide full specifications and dimensions.
Scope of Work

Design a custom air shroud that bridges the gap between the fans and the passive Dynatron heatsink, directing airflow through the fins
Optimize the geometry for a clean, snug fit and minimal airflow leakage
Design for FDM 3D printing on a Bambu Lab X1C — if the part exceeds the build volume, design it as printable sections that assemble together
Apply design-for-additive-manufacturing best practices: sensible wall thickness, minimal/clean support requirements, appropriate print orientation, and tolerances that produce a snug fit
Account for the thermal environment — the part sits in the airflow path near hot components, so it should suit a higher-temperature filament (e.g. PETG, ABS, or ASA) rather than PLA. Flag any material recommendations.

** Deliverables **

Editable source CAD file (e.g. Fusion 360, SolidWorks, or STEP)
Print-ready file (STL and/or 3MF)
Recommended print settings / orientation notes
One or two minor revision rounds after a test print

** What We'll Provide **

Detailed specs and dimensions
Fan and heatsink layout / positions

** Requirements **

Proven experience with mechanical/functional CAD design
Demonstrated experience designing parts for FDM 3D printing (please share relevant examples)
Familiarity with Bambu Lab printers or comparable enclosed FDM machines is a plus

Understanding of airflow/cooling design is a strong plus

We are looking for a FreeCAD specialist to work long term on turning plans into full parametric CAD drawings within FreeCAD.

This is hands-on production engineering, not concept design. This role is FreeCAD-native. This is not a Fusion 360 / SolidWorks / Onshape job, and we're not looking to switch tools. Please only apply if you're genuinely strong in FreeCAD.

What you'll do


Build fully parametric, spreadsheet-driven models (parametric tables).
Maintain a robust master-model library - properly constrained sketches, sensible aliases, and models that don't break when parameters change (managing FreeCAD's topological naming behaviour where it matters).
Produce CAM in FreeCAD's Path / CAM workbench — operations, toolpaths, and clean, production-ready G-code.


Must-haves


Demonstrable, in-depth FreeCAD experience — please include examples or a portfolio.
Strong parametric-modelling discipline: spreadsheet-driven design, aliased parameters, robust constraints, and a real handle on keeping parametric families stable.
CAM / Path workbench experience producing G-code that actually runs on a machine.
Reliable, communicative, able to work independently and document what you build.


Strong pluses (and where this is heading)



Post-processor development / customisation experience.
CAM optimisation: adaptive / trochoidal toolpaths, and nesting for sheet materials.

To apply, please include


Examples of your parametric FreeCAD work — ideally something spreadsheet-driven, plus an example of CAM / G-code output if you can share it.

We are seeking a highly experienced SolidWorks designer/engineer to take an existing working prototype model and rebuild it into a clean, fully structured, fabrication-ready parametric design.

A functional SolidWorks prototype already exists. However, it requires a complete professional rework to align with best practices for parametric modeling, weldment structure, and long-term design scalability. In addition, we are making significant design changes from the current prototype, so this is not just a cleanup — it is a redesign and optimization effort based on an existing baseline.

Scope of Work:
Rebuild an existing SolidWorks prototype into a properly structured parametric model
Apply SolidWorks best practices for part/assembly architecture and design intent
Reorganize and optimize weldment structures for steel fabrication
Implement clean, scalable parametric relationships for future design variants
Incorporate major design changes from the current prototype (not a direct copy rebuild)
Ensure manufacturability for steel fabrication (cutting, welding, assembly)
Produce fabrication-ready drawings, including cut lists, DXFs, and BOMs
Improve overall consistency, modeling logic, and revision flexibility

Required Experience:
Expert-level SolidWorks (especially Weldments and parametric modeling)
Strong experience redesigning or rebuilding existing CAD models properly (not just new builds)
Deep understanding of steel fabrication and structural design
Experience with weldment best practices, cut lists, and assembly organization
Ability to translate an imperfect prototype into production-quality CAD architecture
Strong attention to design intent, consistency, and scalability

Highly Preferred:
Product design and industrial design background (strongly preferred)
Experience with outdoor steel structures, park equipment, or rugged commercial products
Background in fabrication shop workflows (laser cutting, tube steel, welded assemblies)
Experience redesigning legacy or prototype CAD systems into production-ready systems
Mechanical engineering mindset with strong practical fabrication awareness

Deliverables:
Fully rebuilt SolidWorks parametric model (clean architecture)
Updated weldment structure with correct cut lists
Revised assemblies reflecting new design direction
Fabrication drawings (DXF/DWG + PDF drawing sets)
BOM and material breakdown
Editable model structure suitable for future iterations and product expansion

To Apply:
Please include:
Examples of weldment-based SolidWorks projects
Examples where you improved or rebuilt an existing CAD model
Brief explanation of your approach to parametric modeling structure
Any fabrication drawings or steel product design experience
Relevant product design / industrial design portfolio (if available)

We are looking for someone who can take an existing functional prototype and turn it into a professional-grade, scalable engineering model suitable for manufacturing and future product expansion.

Nous sommes Essio Solution, entreprise de rénovation du bâtiment située près de Lyon (France). Nous construisons une petite « tiny house » transportable qui servira de modèle d'exposition permanent devant notre dépôt. Nous recherchons un ingénieur structure expérimenté pour concevoir l'ossature métallique porteuse.

IMPORTANT — L'ossature ne sera PAS démontable. La charpente sera SOUDÉE et transportée d'un seul bloc (sur remorque / levée à la grue). Elle doit donc être conçue comme une structure rigide soudée, avec des points de levage dimensionnés.

• Avez-vous déjà conçu des structures métalliques destinées à être transportées ou soumises à des vibrations (remorques, Tiny Houses, conteneurs) ?
• Pouvez-vous me montrer un exemple de plans de fabrication et de liste de matériaux (BOM) que vous avez déjà réalisés pour un client ?
• Quels logiciels utilisez-vous pour la conception 3D et pour les calculs de résistance (FEA) ?
