I had to file the rca holes down a little to get it to fit, and it was still a tight fit, so you might want to make those holes a little bigger (about .2mm diameter bigger might work?). A little filing was needed for the button holes, but I didn't want mine to be too loose so I left their opening diameter as is. I removed the vent holes as I don't see this as needing them and didn't want dust and hair in the box. The antenna just tucks in when putting the top on.
The author remixed this model.
