The file 'Doodlebob Item Holder 3D Printer Model' is (stl) file type, size is 51.06 KB.
My partner wanted me to make this for a friend so I am posting it here too. Adjust the size to fit whatever you're trying to hold. Solidworks super scaled it but 10% scale fits about a regular joint and 12%-15% fits pens and pencils. I haven't tried markers but you get the story.
