Segmented Square Marker Pen Holder Stand

This modular pen holder is divided into three independent parts: a tray, a marker pen holder, and an electric grinding pen storage. These can be glued together to form a single unit. The tray can hold pen holders with a 75x75mm base. The small square holes of the marker pen holder are 14x14mm in diameter and there are 15 individual holes, but it may not be able to hold 15 pens (due to the small spacing, it is recommended to use every other hole or insert pens with a smaller diameter). The electric grinding pen holder section can store two electric grinding pens with a diameter of about 33mm, and also provides two 60x15mm rectangular slots (one closed, one open, for storage as needed), as well as one through-slot and one semi-closed slot.
