Simple notebook stand.

2 pieces so it can be printed without support and then put togheter simply by inserting the pin into the stand. You may have to sand a bit the pin to fit it in the stand but I did it like that so it stays in without glue. I pressed it in with a vise.

I used a 1.0 mm nozzle with 2mm walls and 10/15% infill. I suggest printing without cooling and with a bit of brim around so it doesn't warp.

You can put some rubber under it so it doesn't slip on a table.
