Paper Sheet Guide for Brother ADS-1800W

I own this Brother ADS-1800W Scanner which work great except for the capabilities to feed the paper sheets straight wihtout an angle. So I made these small helper guides. They just need to be clipped to the scanner. I lackes it funkction to be closed with them attached but I have it standing around open anyway. I use it for a couple of weeks now and the scanner works much more reliable.
