Configurable Angled Filament Feed for Dry Box

Update 2018.03.05

I added a jig to help drilling the hole at a 45degree angle. Note that when you drill a hole through your plastic box, be very careful that you don't crack it. I would start with a pilot hole first and then make sure that a sharp wood drill is used instead of a dull sheet metal or masonry drill bit. And drill slowly to avoid cracking the case.

Use a 11mm or 7/16 drill bit with the jig to drill the right sized-hole at an angle.

Also added 13mm hole version for 1/2
