Building on the excellent hyperboloid design by stuffperson, this thing holds 8 pens with a diameter up to 11 mm plus 8 more pens or pencils with a diameter up to 9 mm. The hole sizes alternate to avoid holes intersecting. in addition, the PLA used was Rainbow Silk which gives a very striking effect.
