This is a Hulk calculator only for cool boys ;-). It looks like an easy and quick project but I really had to use my (mathematic part of my) brains again because I have a small calculator at home that I opened and the actual calculator, especially the rubber keyboard needs to fit in. I don't remember the last time I had to use my mathematic skills so much like now....

Tutorial

I googled to find an image of Hulk that I like for the silhouette of the calculator.

Then I inserted the image by clicking on Insert Sketch.

I traced the silhouette of Hulk and sketched a square for the rubber keyboard.

I calculated the cover of the actual calculator and sketched all the lines. This part was the most difficult part because you need precision work.

Here you see how complicated it looks like. You need to have some mathematic skills for this. I am still not sure if I did everything correct because it wasn't easy to measure the actual cover for the rubber keyboard.

I extruded the Hulk cover and leaving the square holes.

I extruded the Hulk again where the calculator and keyboard will be inserted. I made it 9 mm thick. I offset the silhouette of the Hulk with 5 mm. The calculator needs some support so I sketched a square and extruded with 4 mm.

Creating the keyboard holes was the most complicated part but tracing the face of Hulk was taking most of the time.

The Hulk calculator exists of two bodies. The upper body is the cover, which is a very thin part of the calculator. I am very curious if everything will fit and if the print will be a success since it is very thin. Let's wait and see.
