My Video Review of the Yoctosun Magnifying Glass 

This video is about a #D Printing Tool that I find to be very useful, when it comes to the 3D Printers, that are either "Bed Slingers" or "Core XY" 3D Printers.
This is very useful in magnifying the tiny screws when either assembling, or repairing the "Bed Slingers" or the "Core XY" 3D Printers, because it is hard to see the holes that can be about as tiny as the screws are as well. I have used this multiple times, and will continue to use it on either the "Bed Slingers" or "Core XY" 3D Printers that I have currently.
This has a USB Cord along with it, for when it runs down on power in the light part.
You can find this at the following link at: www.amazon.com...
I seriously recommend this product. It helps me out a lot with my 3D Printers, when I am going to repair them or do maintenance on them
