Sometimes a 3D printer is useful for making things that solve actual problems. This is one of those times.
My grandma's new place has coffee and other hot drinks available in disposable cups. The cups work perfectly well at containing coffee, but they get hot to hold, don't have handles, and have narrow bottoms that make them a little easier to knock over than I would like.
So I designed a holder around them.
The disposable cup still handles the beverage-holding responsibilities. This adds most of the features I wish the cup already had: a comfortable handle, some insulation from the hot beverage, and a much wider base for stability.
The cup simply drops into the holder and can easily be pulled back out when you're finished.
Make It Your Own
I originally designed this for Grandma, so leaving it completely generic seemed like a missed opportunity. Her favorite animal is an owl, which is how an owl ended up on mine.
But you don't need to modify the CAD model to personalize yours. You can use Bambu Studio's color painting tools. Simply import the cup holder into Bambu Studio, grab the paintbrush, and add leaves, names, patterns, or whatever else your mouse-based artistic abilities will allow.
The painted areas become part of the print rather than separate decorations that need to be glued on afterward. That makes the same basic model easy to customize for different people, holidays, seasons, or for no particular reason at all.
Printing
The model is designed to print as a single piece. No assembly is required. Just print it, drop in a disposable cup, and you're ready to go.
If you make one, I'd love to see what you come up with, especially if your Bambu Studio painting skills are substantially better than mine.
