You could use this for a number of things, I like the candle idea but I also thought about making one as a plant stand. You can get very very creative with these. And they are not very difficult to make.
Step 1: Grab some scraps
Grab a pencil spring punch or scratch awl and mallet and your angle square for the next step.
Step 2: Layout for the holes
Then using a spring punch make a divot. Then I used a compass and made a circle as large as the block would allow, then made another circle about 1/2"-3/4" less in radius.
Then, I used the center punch and made the first divot for the legs. The location of the first divot doesn't really matter.
Now, without adjusting the compass from the inner circle size, start at the first divot you made and make 6 perpendicular marks moving from one cross-mark to the next as pictured.
Finally, using the spring punch, divot every other mark leaving 3 divots in total plus the one in the center.
I then drilled the center hole to allow my worm drive for the chuck.
