This challenge is to create a CAD file that I can use to 3D print the item. Would also love to have a few images that can be used for a presentation. Attached is a design that I created in Word

I am looking for a utility knife design where the blade can go from cutting, to scraping, without removing the blade from the handle. The knife should preform like a normal utility knife when cutting. Then the blade edge would have to be fully exposed, and locked into a "T" shape with the handle, allowing the knife to scrape a flat surface. The blade should be the standard, trapezoidal utility blade. The blade would have to fold or slide into the handle when not in use.

At Fluidity Marine, our mission is to develop sustainable and eco-friendly marine technologies that push the boundaries of performance, efficiency, and environmental responsibility. We strive to revolutionize the marine industry by creating innovative solutions that reduce environmental impact while improving performance and safety. Our goal is to lead the way towards a more sustainable future for the marine industry and promote responsible stewardship of our oceans and waterways. For our initial fundraising efforts, we require some conceptual artwork of novel and theoretical designs for 3D Printed Hull designs across an array of hull types (Pontoon, Semi-Displacement, and Planing Hulls) all with modular electric motors and water jet, impeller based and rudderless propulsion. Dynamically deployed hydrofoil systems with integrated impellor jet systems are encouraged. We have basic sketches of an array of designs attached to the project, but would appreciate extrapolation and creativity in so much as the designs are either: 1) Completely novel hull designs only possible with 3D printed manufacturing 2) Integrated flat nozzle water jet arrays without rudders that navigate based on flow control of jets on one side or the other. 3) Aftermarket Retrofit devices that can be attached to existing hulls to convert traditional hulls to electric propulsion. 4) Foiling Impeller Systems that extend on-demand from the hulls (integrated and aftermarket) 5) Solar and Wind generated energy systems integrated into the shade structures of the boats. Particularly Flexible Solar Cloth as Biminis, Gorlov Helical Turbines mounted horizontally on shade structures underneath rigid solar shade structures above them. 6) Automated Solar and Wind powered barges, docks, and other marine support structures. Seed Deck Investment pitch attached with sketches for additional context.

I'm looking for someone who a can conceptualize, design, make 3D model and make animation of the packaging machine for an African traditional food packing method as shown in attached video. In which, for a single cycle we just have to put the leaves one on another in machine and feed the food somewhere so that it can be laid on to the leaves and then rest of the packaging process be carried out by machine itself while operated manually. The final packaging should look as close to the original hand packaging as possible. The machine should be manually operated and not electric one.

I need help creating a sketch. I'm not a good drawer I need a drawing of a pulley A/C compressor. When the pulley AC compressor turns it runs normal. But when turned off a mechinal ball pushes up allowing the pulley belt to turn freely.
