A stand for pilot pens that does not take up much space

I often use pilot pens, so I designed an object that fits on my desktop and allows efficient, orderly and accessible storage of 6 pilot pens in a way that does not take up space from the table.

My desktop is 19.5 inches thick, but I uploaded the SolidWorks file and also a step file to allow  you to fit the file to your desktop

Note that the connection between the part and the table should be tight

The top of my desk is starting to come off the table which has created a kind of spring effect thanks to which I did not have to use glue at all - but there is a chance that you will have to

Between the pictures I put a picture of the part on the print bed - in the orientation where the part is placed there is no need for supports 

(In the picture I used Raft - you don't have to use it, it's just a problematic printer)
