Prismacolor Pen Notebook Holder

Prismacolor Pen Sheet Holders I wanted to develop sheets that could stack and stick into a bag or zip-folder/binder These are stackable; you can organize pens by color/hue Print individual sheets in a different color as needed; I printed in black PLA for the black/grey tone pens The sheet will print flat; once you start popping pens into the holder slots it will produce the arc naturally. The current model may need to be scaled to fit other markers; the current model fits Prisma
