Side table for IKEA POÄNG chairs and stools

I created these simple tables to hold my morning coffee or a book as I enjoy the sunrise. The table is 160x160 and slips onto the side of the IKEA POÄNG chairs or the footstools and stay in place. 

I have created 3 versions. 

1. A version is a simple flat table that can be used to hold anything you want or a mouse pad.
2. A version with a small lip on it to prevent accidentally pushing the coffee cup off with your arm. 
3. A version with an indented circle to hold your coffee but won't get in your way if you want to put something flat on there.

I started down the route to create a much more complex table but this one won out due to the ease of printing and the simplicity of the design.

I have printed this in .3 and .1 layer heights on various printers and both seems to work. Best to print on one of the ends. I chose to include supports for the build plate to increase the connection to the build plate.
