1, 2, and 3) are not really "napkin sketches", they were refined sketches. At this stage all the dimensions are in Millimeter.ġ23D is a 3D CAD or Solid Modeling Application for Windows. The other consideration is that the design should compliment the existing object. Later I would refined the napkin sketches to realizable design and something that make sense. Sometimes I only doodling on the napkin, just like other designer/inventor did! When I was working on the new project, I usually transfer the idea I had in mind into the paper. So the designs will somehow have the round plug attached to one end, as shown in the sketches below. And both shoulders and hand will be fitting into round Acrylic tubing with 1" (25.4mm) OD (Outside Diameter) and 7/8" (22.225mm) ID (Inside Diameter) . I designed the ears, eyes, shoulders, and hands for my robot project, Put 40 LEDs and Brain into Robot Head.Īll the parts are only decorative pieces for the robot, only the eyes that I may want to put the 5mm diameter LEDs inside.Īnd the parts will be fit into the round existing openning, for example eyes will be fit in 10 mm diameter openning, and ears will be fit in 20 mm diameter openning. I will post the picture as soon as I receive it. (which allow you to print a larger 3d model for example a model with a footprint of 4圆", etc.) Note: I submitted the 3D Print file as used in this tutorial to our "Free 3D Printing" Group, but it is still in the queue to be printed. Not only you could use this methods for "Free 3D Printing" here at instructables, but you could also apply the methods with your 3D model to be done ( but not free) at Shapeway, Ponoko, etc. Another benefit of combining (joining) models together is that if the combined model has the size which is smaller than 3x3x3" cube, we could submit the model to "Free 3D Printing" offer to have it made if you are not in a hurry! But you need to write up an instructable and sign up as a member, to qualify. And we could avoid waiting for each part to be delivered many times before using them in the project(s). We could save time and do not have to submit each part individually. By combining (joining) small individual 3D Models together, either from the same project or from different project. I will introduce to you various methods to create 3D models starting from basic drawing methods as used in creating ear and complex methods to create 3D models as used in creating eyes with eyebrows.
