This is a Tablet / Phone Cradle to attached to a monitor stand without screws. It is big enough to support most tablets and small enough for most smartphones. My monitor stand has a 45 degree bevel on the front face (Unlike the Ikea or other monitor stands) so needed something to accommodate that.

No brims should be needed. Standard settings should suffice. I printed mine in PLA.

I did add some electrical tape where the cradle clamps to the stand. This should help protecting the finish on your stand and will allow you to dial in the fit. This was designed to work on the stand that is 18 mm thick. May work on a ¾ as well
