Eachine VR D2 Pro - Lens focus adaptation

Print the lens template and use it to draw and cut the original one. Yo also can buy and try with a fresnel lens https://www.amazon.es/dp/B00ZPS7NO8?th=1 and cut using the template. If you are happy with the results then you can try with the original one.

Print two sliders and replace the orinal ones. You will have 2 new posistions in the slider to put the lens as close as necesary to your eyes in order to focus well.

I also provide the slider.gcode. You can use it to print it diagonally
