Ellipse_Guides_(170x115mm_10-80deg)

Proper elipse guides are still very expensive and hard to find. So I decided to design and make my own. 

Idealy you want to print them in transparent filament to help you position the elipses better, but it works even with non-transparent one.

I made the guides only 0,4mm thick. If you need something more heavy duty feel free to change it.

I also added simple measurment tool on every guide (marks are every 5mm).

Let me know how it works for you. I may upgrade it based on feedback.
