This is one of my first designs using OnShape. The photo is a print from a MarkForged x7 with Onyx.
I specifically designed this for the metallic markers that should be kept point down so the tip doesn't dry out. This design lets you hold both types of Sharpies while still seeing the cap color.
You can download the STL from or get the original cad document from OnShape (you might need a free account)
