This is an adjustable money clip inspired by legos. With these pieces that I have CADed, it is possible to put different size stacks of cash in this money clip by removing the blue piece and placing it in another position. This was CADed in SolidWorks and the tutorial assumes that you have a basic knowledge of the program.
Step 1: Finding Dimensions
First, I found the dimensions of legos to make sure that the pieces would fit together properly. (Note, I adjusted the height so the clip would not be too bulky). The website I used was http://www.robertcailliau.eu/Lego/Dimensions/zMeasurements-en.xhtml.
Step 2: Linear Patterning
After this I began CADing. (Note: You should never go directly to CAD. Always make design sketches first. I made a couple models and wasted a ton of time since none of them made any sense when I actually put them in SolidWorks).
After extruding a piece of the right size, I dimensioned a single circle, and then linear patterned it.
Step 3: Adjustablity
After extruding these circles, I then created several extrusions on the part so that it would be adjustable.
Step 4: Extrusions for Intersection
Afterwards, I created the bottom pattern by offsetting rectangles then extrude-cutting them. Then I extruded the middle circles. (Again, this is based on the website that had the lego dimensions)
Step 5: Bottom Extrusion
Lastly, I extruded the bottom piece. Pretty simple.
Step 6: Final Rendering!
I created the blue piece pretty much the same way that I did the top part of the red piece. Then I created an assembly and made some beautiful renders. And done!
