This is a nice desk accessory, the file contains a small piece that holds the revolving part in place which is easily snapped when printed and rotates nicely, the piece is not visible so do not worry about being able to see it after.This should be printed WITHOUT support, and without brim, print at 200 celcius for PLA and 220 for PLA+. Print speed at 50 mm/s and nozzel height at .02 mm,

This part can hold a pen without falling over it is just the correct diameter base but if you want the piece fixated at a certain spot on the desk i recommend a small piece of double sided tape works great.
