I wanted a cheap tablet stand that didn't look clunky, chunky or obtrusive on my desk. This is what I came up with in about 15 minutes with a chunk of 3" pvc.
I hope you like it enough to copy it.

Step 1: No Pictures of Work in Progess

I did not take pictures of the work in progress.
All I did was cut a 1.5" ring of pvc off the section, mark the lines and cut with a coping saw.
I filed the rough edges and sanded everything smooth.
I painted it gloss black to match the tablet face and finished with clear coat.
