CAD Graphic Designer for Quad Copter/Drone Parts and 3d Printing

General Information I require the services of a CAD designer, to create a stl file (which I will later, send for 3d printing). The person will need to be based in or around London, so that we can meet (either they travel to my home or I travel to their home/office) and explain exactly what is required (dimensions and technical details of the model). Person Specification The person would ideally have previous experience of working with 3d printing and of course, CAD. If the person has an interest in copters/drones - even better. If the person owns a 3d printer - even better (if 3d printing is provided, I shall pay extra for this). Job Specifics I have a quadcopter whose arms are too short. I need the designer to design/create a part, which can be fitted onto each of the existing arms of the copter, to extend them. When I meet with the designer, the designer shall be shown the copter, so he/she can take measurements, etc. The designer shall be working with me, creating the design on screen, while I explain to him/her what I need the new part to look like. I already have a good idea of what the part should look like so the design session should be fast. I shall need the resulting CAD file, as well as the stl file (which shall be used for 3d printing). What I need a quote for I expect that that the full job will take 3-4 hours. I suggest that you quote me for 3 hours work + additional price per hour (after 3 hours). If the person travels to me (Harrow, HA1), I shall pay up to £10 extra to cover their travel (proof of travel cost shall be required). Should this first job go well, the person shall be hired for further sessions on an ongoing basis, as the copter is being prototyped and continually developed. Attached is an stl file of the copter arm. The part(s) which needs to be created will need to fit this copter arm.
