Plugging small hole in acrylic

I have an acrylic tank with a rear overflow box in which was drilled a small hole -- maybe with a 1/4 or 3/8 bit. Small hole. It's about 1/2 down the overflow. Don't aske me why. It's not a problem for me, because I use the drain in the overflow for a closed loop not a sump.

The overflow, however, also has a second hole in the bottom that currently has a plugged bulkhead. I'd like to use that for a return (that will then go up over the top with pvc.)

In short, I have to do some work inside the overflow box and would like to drain it without draining half the tank. Is there something I can use to plug that hole for a day or so while I work down there? Anything more permanent? Way too small for a standard bulkhead, I think. Can I make a DIY bulkhead/plug for a small hole?
