Here is a mini-kit to get your 16x2 LCD standing up straight on your table. Made of 3mm black acrylic pieces, with 4 x 1" nylon screws & 4 x nylon hex nuts, it goes together in a jiffy and looks super-spiffy!
OLED 16x2 displays and RGB backlight positive and negative LCDs have slightly smaller screw holes so you'll have to drill them out to fit the #4-40 screws if you want to use them together.
Character LCD not included!
We have a lovely tutorial on assembling the stand and setting up an LCD system monitor for Windows, Mac or Linux/Raspberry Pi computers
