Hi Mpones,

Here is a DXF of your design.

Iserted the image, traced it manually in Autocad and then deleted the bitmap to leave just the line and arc geometry....
There are just 48 objects.

If you know the slot widths / overall size, it can be drawn exactly to scale.
My size is a guess, I supose the item could be as big as a battle ship
