Whiteboard angled pen holder

thingiverse

This design accommodates Explor vis-a-vis pens specifically. The pens themselves measure 10mm, while the tubs stand at 11.5mm tall. To accommodate larger pens, scale up your prints as needed. By default, these designs fit three pens to a single large Command Strip and are engineered to nest flush against one another. Refer to the photo for visual confirmation. The tubes, meanwhile, angle off vertically by thirty degrees.
