Complex Problem Complex Solution: Lemon Squeezer
Description:
Students will explore different software applications for creating a complex 3D prototype design(s). As a class we will brainstorm ideas for replicating and/or customizing designs for common objects that are used to solve routine problems. Examples might include designing a set of gears that will be used in conjunction with an shaft to turn or move another object, a protective device for smart phones (custom designed smart phone case), etc. Detail in specifying measures for design elements becomes essential to successful builds.
Students will use 123d Design and/or Sketchup to “solve” their problem. Objects may need to be imported to Meshmixer for final tweaking and prepping for 3D printing.
Projects then get uploaded to the ePortfolio on a page (kid to 3D Design 2 Build) with the assignment title, the above description of the assignment, the .jpg perspectives, and a reflection statement (what did you do – restate the task, how did you do it – process, and how do you think it turned out).

Reflection: This project was very fun, but it involved a lot of trial and error. Also a lot of tweakage. I have printed two of the hinge version so far, neither of them have worked, so I think that I will go with the grinding version. How I made this was a little bit complicated, mostly because it was a lot steps. First I split a sphere into two pieces. Then I shelled, and put holes in the bottom of the one that was going to be the bottom piece. Then I drew a handle using the spline and polyline tools, then I extruded it. After I had extruded it I shelled it, and attached it to the bottom half. Then I made the top, by subtracting filleted cubes out of the half sphere, I also added a cylinder to make it taller. To the top I also added a handle, except this one was a cylinder. This was the second version though, the first time I tried to make a hinge, but it didn’t end up working when it printed. The final version will not match the pictures in 123d design but you should be able to get the gist of it in the live pics. This assignment was a good, fun challenge.
