Sold individually, and measuring about 5 inches along each side and 3 inches tall, here are some BMF Nagel candle holders from West Germany. They cost 17. each. They are very heavy, which is necessary to be able to stack them however you want, whether geometrically or asymmetrically, or vertically or whatever. Choose however many you would like; the price here is for one. Each candle stick holds a maximum of 3 candles. You cannot get more architectural than this, and what's more you can use it for dinner parties and change it around each time. The side of a triangle is about 5 inches, and the hole is about .5" to fit a .5" diameter candle, which is a standard christmas tree or hannukah candle.
