My first upload - This is an experiment I've been working on for a couple days now while I learn parametric modeling with openscad. I wanted to be able to design and 3D print my own macro pads and keyboard shells without having to do all the work from the ground up every time.

The cutouts in the top of the body will always align vertically and horizontally and are made to fit MX key switches. So far I've tested Gateron Milky Yellow Pros and Kailh Box Jade switches and both have fit beautifully.

With this code you'll be able to generate pretty much any number of columns and rows for your macro pad / key pad with the ability to have or exclude a cutout for a USB plug or something. Since I parameterized as much as I could it shouldn't be too hard to make this suit your needs.

Please forgive how messy the code is. This is my first foray into anything coding-related and I'm proud of how it turned out. Also I had fun leaving the comments in there.

I'll be uploading more models and stuff as I figure them out and get them tuned in the slicers, but here's the base code for now.
