Coffee pour over stand

Pour over is a common way to brew a cup of coffee, it focus on well-roasted coffee beans and slowly extract the taste and flavour from the beans.
One of the most important factor to affect the taste and aroma is the ratio between coffee powder and water, some Japanese experts says that the best ratio is 1:10, 1g powder need 10cc of water.
Another way is Yamada-style, he extract only the first 1/3 of a cup of coffee. That is, only 80cc will be extract if we have 24g coffee powder. It made the measurement become important for a cup of coffee.
I made this pour over stand that could put coffee pot on the bottom of stand, and it has enough room to put electronic scale under the coffee pot.
The hole in the top could fit some popular coffee drip that I've, for example:

• Hario V60 (1-2, 3-4 servings)
• Kono (1-2 servings)
• Kalita wave dripper 155,185
• Kalita HA 101, 102
