Earbud Case

thingiverse

This case is designed to wrap your earbud wire around the middle to keep them from getting tangled. A hole is included in the design to hold the earbud pieces separate from the wire. Project Objectives Students will learn how to use revolve tools and cut parts from a solid. They will learn how curved surfaces work and how they can still be extruded and cut even though the surface isn't smooth. Audiences All ages can use this project for their earbuds when they're not watching or listening to music or entertainment. Preperation Students will need a pair of earbuds to make sure the measurements are useful to them (this design was created to fit samsung earbuds). They need background with the inventor program and know how to use the revolve, ellipse, cut, and extrude tools. Steps Draw a circle 2.625 inches across in the XY plane and finish sketch Create a new sketch in the XZ plane and draw an ellipse that is .625 tall and .876 across, draw the ellipse with the middle point on the bottom touching one end of the top of the circle you drew in step one, finish sketch Extrude the first circle back .625 inches, extrude in the direction of where you drew your second sketch (ellipse) Revolve the ellipse around the axis in the middle of the extruded circle and choose to cut from the solid Draw the hole to clip the earbuds in starting anywhere on either flat surface of the shape, the hole is an ellipse that is .5 inches across and .312 inches high, the bottom middle point should connect to the outside of the flat circle's face. DO NOT FINISH SKETCH Now you have your ellipse drawn, the opening to the ellipse (notch for earbud pieces) has to be drawn .25 along the edge of the main solid, center it and then connect 2 straight lines on either side up to the edge of the ellipse and trim the edge of the ellipse in the middle of the two lines. Finish sketch and extrude/cut the edited ellipse down enough as to only create a notch and not edit the solid underneath Print Results Students will have designed an easy organizing tool that fits their earbuds. Achieving the intentional result will teach how to use revolution, trim, ellipse, extrude, and cut tools in inventor.
