This is for a desktop stand, but U can use longer tubing for a reg stand
The parts you need are a mic clip (should come with your mic), a 3/8 inch nipple (that is what they're called I did not name them) of any length you desire (I recommend the shorter the better), a 1/2 to 3/8 bushing, a 3/4 to 1/2 reducer, a 3/4 inch nipple pipe of as short a length as you can find or want(mine is 4.5in), and finally a 3/4 inch wall flange. The grand total on the parts was $6.70. Average 'non- homemade' desk mic stand costs around $20.
You can also go 1/2 inch on the main pipe and flange and then you don't need the reducer, but while you save a dollar, I like the added weight and stability of the 3/4 inch pipe. I had to go copper for the 3/8 nipple because they only made it in copper and for the bushing it was actually cheaper in copper, and that looks better (At Home Depot at least the keep the copper pipes in a different area, the next aisle over from the main pipe section). For the other pipes I had the choice of black or galvanized. I chose black, I think it looks a lot better.
The one issue is that the pipe thread is a wider gauge, so you can only tighten the mic clip on a few turns but that is enough.
If you like to build things yourself, want to save 12+ dollars, or need a bunch of desk mic stands I think these are great. I recommend bringing your mic clip with you to the hardware store and putting everything together there before you buy, that way you can decide how tall you want your mic stand to be and try different parts
