Divider to turn a cup or drinking glass into an organized pen/tool holder.

Use the f3d file to adjust the cup/drinking glass inner and outer diameters (cup_ID, cup_OD) and wall thickness (wall_thickness) to adapt the model to your cup or make other adjustments for the tools you use.

I use it to keep my most often used tools in close reach, eg. tweezers, utility knife, screwdrivers, pens, rulers.
