Enclosure for DDS Function Signal Generator Module Kit

This is a custom sized enclosure specifically to fit the DDS Function Signal Generator Module Sine Square Sawtooth Triangle Wave Kit found at Amazon.com DDS Function Signal Generator Module Sine Square Sawtooth Triangle Wave Kit

I've attached the OpenScad file I made. Just block-comment the section for the top to render the bottom. Comment out the bottom to render the top stl. Print the top face-down on the bed.

SparkieDave10 suggests printing scaling up 1% for a better fit.
Tolerances are a little tight.
The buttons are a little fragile.
