Description:
We are seeking a skilled CAD designer or engineer to improve or redesign a two-story firefighter training trailer based on a complete draft set of structural plans.

This trailer is intended for use by fire departments to run live training scenarios and fireground survival drills. It must serve two main purposes:

Transport and store full-size firefighter training props

Convert into a modular two-level maze for drills once props are removed

The current draft design includes stair layout, hatch access, anchor point placement, structural framing, wall dimensions, and weight projections. We are providing that full plan as a reference. Designers are encouraged to optimize the structure, improve layout efficiency, or enhance any aspect of the design—while maintaining code compliance and keeping the trailer under 10,000 lbs GVWR for non-CDL towing.

The trailer footprint is 20' long by 8.5' wide and is designed for use on a dual 5,000 lb axle deckover platform. Final designs must comply with applicable OSHA and NFPA training safety standards, including those related to anchoring, railing, hatches, and stair construction. All framing details should be clean, clearly documented, and suitable for fabrication by a welding and construction team.

The goal is a structurally sound, field-ready training trailer layout that combines safety, simplicity, and space efficiency. Follow-up fabrication-ready work may be offered to the winning designer.
Wants:
Clear, well-labeled structural framing

Compliance with OSHA 1910.146, NFPA 1983, NFPA 1006, and 1407

Efficient weight distribution under 10,000 lbs

Smart use of space for maze conversion

Realistic material selection and fabrication approach

CAD file organization and cleanliness
Don't Wants:
Generic box trailer or cargo trailer designs

Concepts exceeding DOT weight or height limits

Non-standard materials or impractical framing

Unclear or incomplete framing documentation
Ask for Sample:
Please include examples of previous CAD work, ideally related to structural framing or trailer-based designs.
Software:
  1. AutoCAD SolidWorks Fusion 360 (Add others if neede

I’m not satisfied with the entries submitted to this contest. Most of them appeared to be AI-generated, irrelevant to the scope, or simply copied what I already provided as a reference. None of the designs met the expectations for originality, clarity, or usefulness. I’d like to proceed with a refund. Thank you.

Hello! This is an exciting and highly functional project—I appreciate the clarity of your brief and the emphasis on real-world application, code compliance, and structural clarity.

With experience in designing modular structures and mobile training units, I’m confident in my ability to deliver a CAD solution that not only meets OSHA and NFPA standards but also optimizes interior space for flexible, drill-ready configurations. I work primarily in Fusion 360 and SolidWorks, with a focus on clean, fabrication-ready framing plans and organized, easy-to-navigate file structures.

I’m particularly drawn to the dual-purpose nature of the trailer and the challenge of balancing structural integrity, weight constraints, and modular usability. I’d love to contribute a smart, safety-focused redesign that can move seamlessly from transport mode to full training utility.

I&;ll be uploading my concept shortly and will include examples of similar structural and trailer-based CAD work for your review.

Looking forward to contributing to this meaningful and hands-on project!

Best regards,
Clinton Johnson

Bamboo Prep Station
Hi! We would like to ask you for your help to create a new kitchen prep station product for the market that will be made out of bamboo. Technical skill or experience with these elements would be helpful. We are looking for a high-quality design with optimum functionality. Use this guide to design a product that is unique, hyper-functional, and pleasing to look at. After the design contest, we want to validate our concept and bring the product to market! Deliverables. All CAD drawings showing everything. Please provide full dimensions for each side/element of the design. Also, provide images showing clearly each side of the unit (top, bottom, front, back, sides. 3D files as well. And static images of all the different angles sent separately. Requirements: 1. We are looking for a very specific product. You can choose to use our EXACT details on HOW we would do it and provide the final details to make it work perfectly (and look nice, consider costs, etc). Possibly adding in some small changes or improvements. This is highly desirable to us. We like the current idea but need it fleshed out and the “Look/Details” finalized. See the description on what we were thinking. 2. You can also choose to make a more unique product based on the ideas presented. This could work but it will be more difficult to do exactly what we want. 3. The product must include a cutting board, food scale, food disposal area for items chopped on cutting board, and containers to put the food in. The idea of measuring the food is also good. Extra “cutting parts/blades” not really desired. We like the idea of an efficient cutting board where you use a knife. Please see the bottom on the specifics of the products we like and why. 4. Size: Flexible. Kitchen product. We recommend a cutting board of around 16 inches long and about 10 inches wide. This is a good starting point. The rest of the details please consider making the different elements big enough but also consider the costs as well. It should be an efficient/space saving product. Easy to be out of the way and not too bulky. 5. The item has to come FULLY Assembled. 6. The more versatility and uniqueness this product has the better. But simplicity, cost in manufacturing and shipping are also very important. 7. Material: Needs to be made of bamboo. All bamboo is ideal and recommended. Some metal and/or glass can also be included. No plastic except perhaps for the scale. 8. High quality and durability a priority. Materials that don’t crack or warp, etc. 9. MORE function is desired. Versatility and function is a huge part of our brand. More STORAGE space or ways to store. 10. It should look aesthetically pleasing in its design. People should look at it and go “that’s nice!”. 11. The deliverables should include full design in multiple angles for CAD drawings. As well as static images of all angles plus 3D files. See our attached file for Specifics.

CNC Machined Bottle Opener
Hello designers! CloudNC is running a competition to produce CAD for a CNC machined bottle opener that we can produce in-house and hand out as gifts to investors, staff and visitors. It should be 3-axis machinable (milling only), designed for manufacture (no incredibly tight radii e.g. or internal corners), and look contemporary. You can recommend a material. Multiple parts/materials are acceptable if pretty trivial to assemble, e.g. with a standard M-thread screw. If you have any questions please get in touch. Good luck!
Bamboo Kitchen Organizer
Hi! We would like to ask you for your help to bring our bamboo snack organizer from concept to reality. We are creating a new snack organizer product for the market that will be made out of bamboo and contain a lazy susan turntable mechanic to it. Technical skill or experience with these elements would be helpful. We want to develop a product that serves the higher end of the market. With quality material and a beautiful modern design. Currently, we already have a vision of what the organizer should look like, but we need to bring our idea's to 3D models that we can use to bring to production. We are combining elements of different products and will use these products as references to come up with a final design. For the overall design two products are almost being "thrust" together to get the initial design concept. And then other products are being used as a guide for the secondary details. There is a specific design in mind for the final product but everything needs to be brought together to ensure a high quality design and optimum functionality. In the attached file, you can find a design document with instructions and several example images of related products (with elements being merged). We want to ask you to use this guide to design a product that has the perfect look and feel. Please provide full dimensions for each side/element of the design. After the design contest, we want to validate our concept and bring the snack organizer to production!
