Filter Holes
So these don't look as good as I had imagined. The process
for cutting these out involved using a 1/4 inch drill bit and
a coping saw. First you drill holes for both the top and bottom
of each cutout. Then you take apart the coping saw and put
it back together in the hole and try and cut as straight as
possible down to the corresponding hole. I had planned on doing
this with a router, but the one I had spun too quickly and
just kind of melted the acrylic and then spewed it all over
the place in its molten form. Be careful.
