Project Presentation


Umbrella Joaquin


In this project snap wanted to create something to use in my daily life, umbrella bag for my son. Perform the initial freehand sketch, taking into account as of the umbrella dimensions height and diameter of my son. I had some drawbacks to draw splices or joints. Also I thought of a basket to store eggs and table, the curtain will projects in the following weeks. Below the plane of the umbrella shown.





All parts of the design on the umbrella Inventor and exported to "dwg", a total of 7 rooms, some shown below.






I had enough trouble importing the " dwg " format file to " Corel Draw" , apparently the problem arose when extruding parts in Inventor, I should have just generated or 2D Sketch , then I had problems on the version of " Autocad (2014 ) " , the" Corel Draw " installed version could not stand , I had to record a version of the 2004 extension" dxf " . The conclusion is that best done directly " autocad " or " rhino" .




After much stress and with the support of the support of my FabLab achieve sending the job to the laser machine.

Download cutting files





By printing the parts in the laser cutter.




Then start the work of assembling the umbrella , I had problems at this step in the assembly sequence , you first need to assemble smaller diameter ring with his arms , then the intermediate ring and end the largest . Another problem arose when assembling insurance post , as were small and the material was folded cardboard of these , in the end I could not join. The pole mounted just stay under pressure . The assembly sequence shown in pictures that follow .















Aca show insurance and I could not insert the holes where they should go in the corner.






It should be noted that the thickness of material considered in all joints, seams and channels is 2.6 mm, ie slightly less than actual thickness of the material, this is done with the intention that the piece is assembled with pressure. Now my model proves "MDF" I'll be posting the results


Vinyl cut

The next job was to create a form, as a sign and then cut in the "Roland GX-24" on vinyl. The way I generated was a sign to place on the umbrella. It was extremely easy, the sign it worked in "Illustrator" and how autocad. I had to be careful when taking off the sign and shape of its base because it moves.






Results in Roland.
