Introduction: OPESK: Parametric Desk

This project uses a Rhinoceros plug-in, called Grasshopper, to create a parametric desk, that can be transformed into different forms, simply by editing a fill options. The file can be exported for fabrication in a CNC Router machine.

Step 1: Open

First, you need to download the .gh file, to edit the grasshopper parameters, or download the .zip file with a few finished models for fabrication. The Grasshopper is only a plug-in, not a modeling tool, so what is make in there is only a preview, until you uses the bake command. As can be seen at the video.

Step 2: Editing

If you are not familiarized with the software, it could look pretty confusing, but the elements that should be edited are all grouped in green box. It safe to change this values freely, but if want to actually send the file for fabrication is best to make sure that you chooses will not result in a poor structure.

Step 3: Finishing

When you are finishing editing you can simply bake the red box element, to generate the 2D file in Rhino, and export it in the format that is required. This project is only a experimentation and its need to bee appropriated, please feel free to help to evolve and refining this idea.

Here's the version on 3/4" Plywood. Not bad at all, pretty stable, got the job done, threw my old desk away.

2 things I learnt in the process :

* Measuring the thickness of your plywood sheet and adjusting the spaces on the cross holes pays off (had to carve it by hand later)

* For the corners, apply this technique of partial circles that are the tool diameter so that the faces touch and you don't need to do 2 tool changes while CNC'ing :

And finally, public link of the design files for my cut if you'd like to reproduce it. One improvement was that the crosses on the table top are now pockets so they won't appear :

Thanks Erickson for providing the design files in a so easy way to reproduce it. I got the Grasshopper files and had to change some suggested limits on it before I could make a much smaller version (my apartment is pretty small).

For the people trying it out - 1/8" plywood is too thin, makes the desk wobbly. I't usable though for laptops and small items.

I knew that it could happen but wanted to try it out in a laser cutter anyway, so here it is. Going for thicker versions in the near future.
