DIY Worm Bin: Failure to Launch!

Today, tragedy struck my attempt at making my own mini vermicomposting bin.

I had excitedly shredded newspaper into strips to use as bedding material, and had cleaned out an area under my kitchen sink where the worm bin could stay away from sunlight, and have a bit of airflow around it.

Then, I borrowed a drill from my neighbor so that I could create 1/4" drainage holes in the bottom of the top two nested tubs, and 1/8" air holes on the sides and lid as well (as suggested by this DIY tutorial). 

I had a very hard time with the first three drainage holes, and had to apply a lot more pressure than I expected.  Upon trying to make a fourth hole, the bottom of the tub cracked, and a little piece of plastic even came out entirely!  The difficulty turned out to be because I had the drill set to "reverse" :-P 

I decided not to worry too much about it, since I only needed two tubs to start with anyway - one for the worms, and one under it to collect the drained worm juice.  The third tub only comes into play when all the bedding and scraps have been converted to castings in the original worm layer.  I figured I would just go to Target later and get another tub.

I corrected the direction of rotation on the drill, and began drilling drainage holes in another tub. I quickly learned that I didn't need as much pressure now that the drill was working in the proper direction, but I guess I weakened the plastic with the force I used in making the first hole, and this tub cracked as well!

I decided to just save the third tub and its intact lid for some other purpose around the house.  

Back in the fall when I made my own Bokashi bucket, the plastic buckets I used held up just fine to drilling.

If you're trying to make your own worm bin, I would NOT recommend the Sterilite "RE-organize ShowOffs" for this purpose!  I had high hopes for these Target tubs due to their modest shoebox-like size, but the plastic seems too brittle to withstand drilling.

Now I am back to square one, and in search of small containers I can use to build my worm bin.  I know that people have had success with Rubbermaid brand tubs, which are made of a different plastic than the Sterilite containers - with the added benefit of being opaque.

I found this 3-gallon Rubbermaid tub online that would probably be small enough, and is marketed as "shatter-resistant."  Does anyone know where these are available for purchase?  I haven't seen this size at either Target or Home Depot around here. (Oddly, one of the top Google hits for the 3-gallon roughneck tub is for Blain's Farm & Fleet, which we have in my hometown in Illinois.  Unfortunately, I'm now 2000 miles from there).
