The file 'Horizontal Pen Holder 3D Printer Model' is (f3d,stl) file type, size is 259.1KB.
Very simple pen holder that allows to store them horizontally - when in a drawer for example, and it's not high enough to allow vertical storage. The slits on the sides allows for easy grabbing of a pen.
I provided the original Fusion file if you need to modify.
