Please read full listing details. this is one of many cup holder spacer styles and designs I make. 
 
I made this to hold my drinks from falling out of the cup holder on Freightliner Thomas school bus. I also added a spot to hold pens or pencils.
 
I have been told by people that have ordered it that its fits some Freightliner  semis and the S2RV chasse with the same style of cup holder that is in the pictures. If you have a different style looking cup holder please look at my other listings or reach out.
 
***will not fit freightliner  classic or Columbia. see other listing for classic style cup holders****
 
This is  1 of 3 styles of the cup holder spacer I make and sell. I also make a taller one and a slim one for larger cups.
 
UPDATE: I have added the option to order two pins that slip into the pen/pencil hole to hang stuff from, please see other listing for them.
 
inside size 77 mm +/- 1 mm
 
UPDATE: they also fit MV International trucks. see the last two pictures.  see other listing for can holder that drops in for the MV international

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.
