I made this to help fill in the holder so your drink won't move around and splash and hold a pen or pencil
 
You will need to order the magnetic cup holder from Amazon.

CLIMATE NOTE: This is printed in PLA plastic which is known to warp in higher temperatures or become brittle when exposed to UV light. If your car is in a hot climate and in the sun, the high temperatures (>125℉) and direct sunlight could warp this adapter or cause it to break. This particularly applies to places like Phoenix, Southern California, etc. where temperatures regularly reach into the 100℉. An average "hot" summer day in Minnesota, or Wisconsin, or New York could also warp these if your car sits in the sun! 
This product is 3D printed. Due to the nature of 3D printing, there may be a seam, layer lines, and/or small imperfections.
Washing instructions: Hand wash only with cool, soapy water. Rinse and dry.
