Picture of 3D Printable No Tip Cup Coaster
If you have young children that aren't too careful with open cups, or if you'd just rather not have to worry about accidentally elbowing your drink, then this convenient little holder would help you out a lot. It keeps your cup from tipping over easily, AND acts as a coaster to protects your tables and counters.

This Instructable is going to show you how to make a 3D printable drink holder on 123d Design  ( ) that drastically decreases the chances of your drink tipping over, acts as a coaster, and can be washed. 

Now, the attached is an stl. file of the holder I made (No, the poorly made soda can isn't included). It will fit drinks with a diameter of 7 cm or less (most soda or beer cans, bottles, and cups). You can download mine, or If you want to make a larger or smaller holder, I'll leave a formula at the end of this Instructable so you can plug in your own measurement, get the angles right, and have a holder that's to scale when printed!

First thing is first, download the desktop version of 123d Design at, open a new project, and change your unit to cm if it isn't already!

To make the inner wall:

1) Make a circle with a diameter of 8 cm
2) Extrude the circle up 3 cm
3) Move the shape and delete the circle from underneath it
4) Use the shell tool to select both faces (top and bottom) of the cylinder you're working with, and make it hollow with a thickness of 0.5 cm

I'm just getting started with 123d and as someone completely new to 3d printing software I found your instructable very helpful. I followed your instructions step by step and I'm now a little more familiar with 123d. Thanks for teaching me some new tricks!

When I became disabled, I had a real bad problem where my hands would shake uncontrollably. After knocking over my drink as I tried to reach for it, I decided I needed something to give stability in spite of my non stable hands. I use a standard roll of tape, duct tape or masking tape. I fold a paper towel in half, set it on top of the roll and press down with my glass to form an absorbing barrier between the glass and the roll of tape. It has worked beautifully! However I would much rather have something more aesthetic and doesn't take quite as much space. This looks perfect! Thanks for sharing!
