Adding a hose barb to skimmer collection cup

I'm putting a drain in my collection cup and I would like to put an angled hose barb right into the bottom of the cup.  I found some threaded hose barbs at Menards, but I couldn't find a tap that matches the threads.  I would like 3/8" to match the hose barb on my skimmate collector.  Who has done this?  Did you drill a straight hole and use a rubber gasket and nylon nut, or tap the acrylic and thread the barb right in?  Interested in seeing the different methods that people are currently using and welcome any advice on how to tap the acrylic collection cup without screwing things up and ruining it.

I think I'm going to go with the drill + nut option. I think tapping it is going to be more hassle than its worth. Also, I'm going to retrofit it with quick connect fittings vs. clear flexi tube

OK, so it's all done.  I used the nut/rubber washer approach, but the problem was, I couldn't find a nylon nut or a rubber washer to fit the 1/2" quick connect fitting.  I had to improvise.  I took a 1/2" PVC threaded cap and cut the enclosed end off of it leaving me with a threaded nut.  I also had to make the rubber washer out of rubber washers that were differently sized, but gave me a large enough diameter..so I just cut the hole larger.  Finally, I cut down the end of the quick connect bulkhead so that it did not extend past the end of the PVC nut.  Finally came the drilling of the collection cup.  A drill bit large enough would have cost $15, so I bought a set of cutting bits for my Dremel and made the hole by hand.  I put a piece of tape on the acrylic with the circle on it the size that I wanted to cut out.  I had to do the same thing with the skimmate locker to make the hole just a bit larger to accommodate the larger bulkhead.  I had never cut acrylic like this before and it worked better than I expected.  Images of the finished project are below.
And to all of you that gave recommendations on how I should do this, thanks!
