Open Sharpie_Holder.scad in OpenSCAD or the Customize option to modify these to almost whatever you need on a hanging Pen/Pencil/marker holder. More options are available in OpenSCAD than with Customize.

I renamed technojunkie's "name" field to "Raised Text"

I added the ability to add screw holes to the "top" and to pad the top, bottom and sides (to help get multiple different holders the same height, for instance).

I added some automatic (or manual) adjustments to correct issues which "could" occur when using large angles.

Added a whole bunch of modifiers so you can hopefully get whatever you need from a pen holder (desk or wall). If you change the shape of the towers, remember to increase the diameter (since the other shapes fit inside of the usual circle).

I added the ability to move some elements (Text or pen holes).

The chin size is controlled by the Font Size (set Font Size to 0 to remove chin and text).

Use Vert_Stretch to override the default separation of towers if they overlap (or are too close). Values 1-5 work in most cases.
Use Tower_Adjust to move the full set of towers (keep them attached to the base).
Use Text_Adjust to move the text higher or lower than the default.

Quick Tips
I use -60 degrees for wall mounted pen holders.
When using Vert-Stretch set your view so you are looking directly into the tubes and increase the Vert_Stretch until all tubes are separated (2.0 worked for me with the -60 degree angle)

Also, all models (-60 degrees) were printed without supports on an Ender 3 V3 SE.

The 3 in 1 Holder in the photo was created by making 3 separate holders of the same height and merging them in a slicer (in this case Creality Print). It took approximately 15 hours to print.
