5V to 3V33.3V logic level converter

I am trying to connect an ESP8266 module to an Arduino. Giving the fact that ESP8266 runs at 3V33.3V and the Arduino at 5V i need a logic level converter from 5V to 3V3.

Is there a way i can build one using discrete components? I searched the web and found recommendations for TXS0104E / 74LVC245 / BSS138, unfortunately none of the local shops sell them.

Although the 3V33.3V TX pin from the ESP8266 does not require a logic converter since Arduino will read the 3V3 signal as HIGH, i would like to add some protection for the wifi module. Is a 3V33.3V zenner diode a wise choice for this? Thanks.
