Silhouette Sharpie Adapter

This is a Sharpie ultra fine Pen holder for Silhouette plotters.
It is designed for the Portrait, but it should also work with the Cameo plotters.
An M3 screw and nut is required for the clamping, to prevent the pen from being pushed out.
In the best case a thump screw like in the pictures.

print settings:

I printed it at 0.15mm resolution with petg.
When printed upside down, there is no support needed.

Update:

I added a 2mm shorter version to get more pressure on the Sharpie's tip. (Ending 28mm)
I also added the step file for an more easy remix.
