Designing the 2D Model

I wanted to create a small model of a laptop pad to stop it from overheating using Draftsight and then use the laser cutter to cut it.

Draftsight

Here are the commands I used to create the drawing:

L to draw lines

C to draw circles

Co to copy

M to move

Tr to trim

Sc to scale

T to add text

Modify à entity à polylineàjoin to join lines together into one polyline

Then I wanted to add an image of the FabLab logo to the design so I used Inkscape CHECK Inkscape section below.

Then I modified the design to be more practical and use the material more wisely so I added a text just to test the engraving function.

I also created another small shape to calculate the kerf and make sure that the joints would fit perfectly.

Inkscape

I used inkscape to get the outlines of the logo photo as I intended to put it on the design then I changed my mind.

Conclusion

I believe the kerf was very precise and accurate. In fact everything fits perfectly in place.
