+### Sourcing components
+
+This section aims to ease the sourcing of all necessary components for the windkit.
+The [BOM](3.Tools and materials/1.Bill of materials) categorisis the components in different categories. These categories also give guidance of where to get what part. 
+
+### Hardware store for component category - COM-STD
+
+* In a hardware shop you should get all parts of the category COM-STD.
+
+### Special supplier for component category - COM-BUY
+
+* All components of the category COM-BUY need special suppliers.
+
+### Self-designed components to manufacture - COM-MAN
+
+#### Laser parts
+
+* Laser parts are self-designed components that are cut out of flat metal plates. Therefore they can´t be bought of the shelf. They need to be manufactured by a metal workshop with an apropriate laser cutter.
+* Each shape of each component is stored in a seperate file 
+* The common file format for laser cutting is ".dxf"
+* The folder ["LaserCutterFiles"](https://git.erni-kollektiv.org/erni/windkit/-/tree/master/Export/LaserCutterFiles) within the Windkit repository contains ".dxf"-files of all components that need to be laser cutted
+* The filename consists of the name of the part the material it´s made of the thickness of the material and the amount needed. See the following example:
+    * UpwindMagnetDiscS235Steel6mm1Pcs.dxf
+    * Name: Upwind Magnet Disc
+    * Material: S235 Steel
+    * Thickness: 6 mm
+    * Amount: 1 Piece
+* Download the files on your local machine
+* You can have a look at the files with the open source 2D CAD software [QCAD](https://qcad.org/en/)
+* Send the files to a local metal workshop with a laser cutter and ask for a quote for the amount of pieces you need
+* After ordering it normally takes 1 to 4 weeks to get the parts
+
+#### Rotor blades
+
+* The rotor blades are build by your hands, according to the section [Rotor blade](???)
