This is a mod to reduce the halo of the Lenovo Yoga Tablet 2 (1380F) 13.3" version and also helps to protect the display surface as it lifts the tablet a little bit from the desk and also the rest of the tablet.ensure that you print the Parts very exactly so they don`t move on the tablet to strong because this may caus to rub grind some color of the tablet of (use at your own risk!). There is also a small lead at the beaming part to ensure it is on the right position when using it.Due to some optical stuff its not possible to make the visor exactle to the size of the beaming surface there has to be a little bit of space to it.the left part (at the powerswitch) has two features:* to ensure the tablet does not wiggle when the beamercap is on and pushed in when not used*to be able to set the tablet vertically to beam to your ceiling and not pressing the volume button the whole time ;)
