This is for my Eyoyo barcode scanner in my library, I needed an angled block to hold the scanner angle down to allow for easier student checkout with a barcode scanner of this type.

My students are able to scan their books easier with a swirling type of laser rather than the line type that is usually associated with library checkout.  The Scanner in the picture also does QR codes so I can scan them to a computer if I need or want to since regular barcode scanners don't have that feature.
