-### Bonus: 3D models!
-
-You currently can view the 3D version of your PCB by pressing Alt+3 (Option+3 on some platforms). It should look something like this:

-
-Oh no! We are missing some 3D models. Here we will learn how you add them.
-
-First, you must find 3D models for your components on the internet, but here is @Cyao's trusty list of common models. (If this opens a new tab and doesn't automatically download, press Control+S)

-
-Note: On some Linux distributions, you need to download the built-in kicad 3d models seperatly, most likely in the form of a package called "kicad-library-3d"
-
-Now open the footprint editor:
-
-<img src="/docs/v2/footprinteditor.png" className="max-w-96" />
-
-In the editor, search for the component you want to add the model to, and double click it, you should have something like this: (I'm taking SK6812MINI as an example)
-
-<img src="/docs/v2/editfootprint.png" className="max-w-96" />
-
-If you don't have your own library yet, click File > New Library... and select Project. Name the library anything you like. 
-
-<img src="/docs/v2/newlibrary.png" className="max-w-96" />
-
-If you want to add a 3d model to a footprint that was supplied by kicad, you need to create a copy of it.
-
-Right click the footprint in the left menu bar and click Copy Footprint.
-
-<img src="/docs/v2/copyfootprint.png" className="max-w-96" />
-
-Search for your library, right click on it and click Paste Footprint.
-
-<img src="/docs/v2/pastefootprint.png" className="max-w-96" />
-
-Now click File > Footprint Proprerities... And you should have a new window, select "3D Models" at the top:
-
-<img src="/docs/v2/3dmodels.png" className="max-w-96" />
-
-If you don't have anything in the "3D Model(s)" frame, click on the + icon. After that, click on the file icon on the right and choose the coresponding 3D model that you downloaded. Now you have something like this:
-
-<img src="/docs/v2/neopixel3d.png" className="max-w-96" />
-
-If nothing is showing, make sure you checked the Show checkbox.
-
-We need to rotate and move it. Press the + and - buttons on the rotation tab until it is at the right orientation, then the + and - buttons at the offset tab until you have the right position. Mine will be like this: (The + and - might be up and down arrows on some platforms)
-
-<img src="/docs/v2/correctneopixel3d.png" className="max-w-96" />
-
-Repeat this process for all the parts that are missing models. If you created copies of footprints, you need to re-assign the footprints to **your own** versions in the schematic editor. Go back to the PCB editor and re-click "Update PCB from schematic"
-
-Now go to Tools > Update Footprints from Library... and click Update on the new window.
-
-<img src="/docs/v2/updatefromlib.png" className="max-w-96" />
-
-After all the work, you will have something like this when you press Alt+3 (Or Option+3):
-
-<img src="/docs/v2/3dwithcomponents.png" className="max-w-96" />
-
-Now to export the PCB as a 3D Model, select File > Export > STEP...
-
-<img src="/docs/v2/exportstep.png" className="max-w-96" />
-
-And select the directory you want the output to be in, then click Export. You don't need to change any settings. In the end you will get a .STEP file, that is the 3D model of your PCB.
