Gridfinity Sharpie Storage Block (Tip Down Version) V2

• 25/04/2024: V2 Version - added cutouts to the sides so sharpies and pens with pocket clips should also fit 4 of the holders now. 
• Thank you @XanderShade01_404080 for the idea. Here is a link to his remixed version. https://www.printables.com/model/299701-gridfinity-sharpie-storage-block-tip-down-with-cli

Sharpie storage block for people who prefer to store their Sharpies tip down as recommended (keeps the tips saturated better with the ink).
