"The smart cup-holder is good for shuttling drinks from the take-out to the office, but if you want to have a cup of coffee while driving..."
I'm used to having real cup-holders fitting real travelling mugs, not just one that sits right below the dashboard or one that only holds cans or small plastic bottles. So I thought it's time to make one on my own.
Step 1: Finished cup-holder first
As you can see, the cup-holder provides easy access to your latte, americano or whatever you prefer.
