LoFi-Ruby - Ruby Guitar Amp Enclosure

This is an enclosure for a "Ruby" guitar amplifier from [runoffgroove](https://www.runoffgroove.com/ruby.html). I modified this file from the original lofipi speaker enclosure, which I really liked the design for. Note that I started with the no wood grain model, and I did not make modifications to the top panel, so you'll need to download that file from the original poster. Also, I uploaded the front cover without text so you might add your own. Thanks to runoffgroove and thenickdude for schematics/files. All rights reserved to their respective owners etc etc...

#### Changes I Made:
* Adjusted front cover style and fit so as not to vibrate, and reduced speaker hole size in cover as my speaker was slightly smaller
* Adjusted front IO to fit required components (switch, 2 pots, guitar jack in)
* Adjusted rear IO to remove unnecessary holes leaving only a slot for a DC jack
* Adjusted front IO panel cover to accommodate new IO
* Removed bottom fan port
* Added standoffs for a 40x60mm p
