Machine Your StructureπŸ”—

To complete your PlanktoScope kit, you'll need to fabricate the structure. This can be done using laser cutting or CNC machining from a sheet of material. You can machine the structure locally at a FabLab or through a company specializing in laser cutting or CNC machining. The cost will vary depending on the material chosen and whether you machine it yourself or use a company.

Get the Plan and Machine ItπŸ”—

You can download the necessary fabrication patterns for the structure here; two versions are available, one for material with 5 mm thickness, and the other for material with 1/4 inch thickness:

Since DXF files don't include unit information, when you open or import one of these DXF files you may need to rescale all dimensions to achieve the correct sizes. You can check whether dimensions are correct by checking the length and width of part M against the actual dimensions shown below:

scale reference

You can also compare the approximate dimensions of parts in the SVG file (for 5 mm thickness material) with the sizes of parts in your imported DXF file to check whether the rescaling result looks approximately correct.
