Drive, relax in your favorite chair, or work at your desk with your mod, remote, tool, whatever... in a safe & vertical position. This will help prevent leaking by maintaining surface tension. When you get a new mod adjust the MODular Cup Holder 2.0 to fit, no longer requires a separate purchase to accommodate! Hold any item ranging in size starting at 60mm wide (2 23/64") by 40mm deep (1 37/64"). Adjust the grip in increments of 2.5mm (about 1/10') to ensure a snug fit. Fits into most cup holders with a diameter of 75mm (just under 3"). Made from PETG to ensure durability and weather resistance via FDM 3D printing.
