Edit 01/2020 :
Added a different version designed to be protected by epoxy resin. See the make for a preview.

This is a round badge for replace the one one the side body of a BMW F800R 2010.
This represent the coat of arms of germany. Basicallyit’s not a nazi thing but the design used between 1928 and 1935 before the change made by nazi.

It was inspired by a BMW patch here : http://f1-wrc.com/images/patches/Motorrad-eagle-patches-5pcs-werke.JPG

The .svg origin is from Wikipedia : https://en.wikipedia.org/wiki/Coat\_of\_arms\_of\_Germany

How I Designed This

Step 1 : Base disc

I have used Fusion 360.

•  Trace a 60 mm circle on a sketch.

• Extrude it to 2mm.
• Made a sketch on the top of your body and trace another circle at 5 milimeter of the first one.

Extrude the edge circle. Now you have the basic surface of the badge. Step 2 : Add the bmw helix

Made another sketch on the top of the previous centered circle.

• On the sketch, trace a cross who represent the BMW helix.
• Ad another circle at 2 mm on the edge.
• Select the top left and the bottom right face and extrude it at 3 milimeters.

Now you’r supposed to have the centered BMW helix. Step 3 : Import the svg

Select the circle face made under the helix. The idea is to import the svg (vectorial image) on this surface.

• Choose import svg
• Choose the dimension and the position on the dialog box.
• Now you have a svg sketch, not perfect but we will work on it. I personaly hide the body of the helix by clicking on the lightbulb on the model navigator. Else I cannot select my sketch well.

Step 4 : Top left and bottom right design

The svg can be imperfect : Some edge are missing.

• Go on the sketch and delete all the line who aren’t usefull for your design. Just keep the eagle.
• Select all the eagle part on the top right and the bottom right by using ctrl + click on them. Don’t select them all but one by one. If you see an error after clicking on a part that’s because a line is missing on the edge. You have to trace yourself a better line and delete the one who are useless.

Choose the « cut » option and finalise the extrusion. At this moment you now have the top left and bottom right parts of the eagle who cut the BMW helix. Step 5 : Top right and bottom left design

Made the sam that step 3 but with the join option of the extrude dialog box : You need to extrude all the eagle design on theses side. Step 6 : Finalize the design

Add some filet on the edge by selecting the circle of the badge and using the key « f » for fillets.

• Draw a sketch an the top circle under the helix with a little rectangle who will « join » the eagle wings. By doing that, you will have a better print by having less retraction.
