Skull And Snake 3D CAD Design

Hello, Looking for a qualified individual to draft a CAD design for a disc golf disc aka frisbee disc that has a standard center core that can be screwed into exchangeable outer rims. The design must be within specs that I have outlined and feature an air tight interlocking design that will not come loose when the disc is thrown or hits an object. Production of this item would be injection molded with TPE.

We are working on developing a nail file. The file will interchangeably use different grits of sandpaper. Attached below is a wood file that will act as a template for your file design. However, there are a few changes that must be made. 1. Our file is going to be single-sided, so the securement method must allow for this. The wood file uses a small wheel that tightens the metal arms to keep the sandpaper in place on both sides of the file, so your design must allow for the sandpaper to be secured at the top and bottom of one side only. 2. Measurements: These measurements can be slightly adjusted to accommodate a good design but it should be close. File length (Not including handle): 4 in File Width: 1 in (I want to use 1 inch sandpaper, so the total width with the rounded edges will slightly exceed 1 inch and that is fine). File Thickness 1 cm (The thickness should be consistent and should not taper thinner at the tip like the attached wood file does) 3. The side edges of the file need to be rounded and slightly raised (.25-.5cm raised). The raised edges will allow the user to hold the file from the sides (similar to how you hold a smartphone) so there needs to be some form of added grip to the rounded side edges of the file. The second picture shows how the file will be held from the side, so the design should incorporate this type of position. The securement method does not have to mirror the wood file. If you have a better design that will hold the sandpaper very securely but is also easy to use/can tolerate a lot of use, this will give you a huge boost in the rankings.

I would like to purchase a full CAD of a rotary filling machine of at least 12 nozzles. I need to know if you have experience in the field. I am wondering if you have a ready CAD that will enable us to speed up the process.

A dynamic model for the performance and environmental analysis of an innovative e-bike The design should describes a performance and environmental analysis of an innovative e-bike by means of a dynamic model equipped with a suitable control for the management of the assisted drive of the e-bike.The main advantage of this approach should consists of the opportunity to simulate different tracks, e-bikes characterized by different parameters (total mass, wheels moment of inertia) and different control strategies.
