DIY Stability Ball Rack

So I have a bunch of stability balls, a bosu ball, and some medicine/slam balls that I need to store and came across some DIY ideas online, so I decided to give it a try.

I started with 14 two foot lengths of 1" PVC pipe, along with 7 tee joins and 4 corner joins.  I assembled 12 of the lengths, using 6 of the tee joins as pictured above.

I cut one of the remaining two foot lengths so that I was able to connect the two sides using a chop saw.  As you can see from the image below, I had to cut the four smaller ones twice because the gaps didn't match up once you pushed the PVC into the joins.

So I cut them again and assembled the rack.  The final result is pictured below.

Update: So one of the things that I noticed was that there wasn't much support in the rack in the middle of the top shelf.  Basically, another medicine/slam ball on the top and the middle would likely collapse.

So I went out and bought another length of two foot 1" PVC length and a cross join.  Basically, I moved the middle portion of the rack from the bottom to the top, and then used the cross join at the bottom.

So as you can see, the middle tee join that was on the bottom is at the top, which allows me to use the two foot length of pipe to prop up the top layer.  I had to cut the full length that was at the top initially into two smaller lengths to connect to the cross join at the bottom.  I will note that I did have to cut about a half inch off the bottom of the cross so that it was the same length.

But it seems to have turned out okay - much more stable.
