I had a hard time finding what I needed for holding my pens on my Multiboard (there are so many parts in the library!). So I just made my own cup that fits on the Multiboard tiles using two Multiboard bolts.

I copied the Multiboard bolts in SolidWorks 2020 (just for the fun of it), so you don't even need to look for the right bolts in the Multiboard library. These bolts are called "Big Thread, Flat Head Bolts".

You get to chose from three types of files: SolidWorks (if you want to modify the design), STL and STEP.
