Cup holder upgrade.
From this.
to this.
Less than 10 bucks.
Ok so here is how it works. the outside diameter of the 3 inch sewer pipe coupling is 3 1/2" which is the exact size to fit inside the cup holder with the rubber bumpers still in place. Use a fine grit sand paper or scrub pad to clean and rough up the surfaces of the fitting and paint with the plastic approved paint. Once it is dry cut the velcro into strips and attach it to the coupling and place the matching side inside the cup holder so it lines up with the pieces you put on the coupling. take a piece of parchment paper/waxpaper or printer paper and wrap the coupling covering up the velcro and slide it inside the cup holder. Once you have it installed and lined up slide the paper out and this will allow the velcro to contact hence holding the coupling in the cup holder and extending it up I have tried a 24oz trevis cup and it fits snugly and securely. Teh advantage to using the sewer coupling is that it is thin walled and dosent take up much space in the inside leaving you room for your beverage. It may not fit everything but just like a car cup holder it will hold drinks much better than the original. Total cost was 10.87$ with tax. I actually done it a bit cheaper as I already had the velcro and paint from another project.
