I'm using 14-segment Alphanumeric displays in various projects in configurations of 4, 8 and 12 characters. Here are frames for individual displays and mounting jigs for combining into models.

Displayed are smart thermometers

• 12 digits: shows temperature, feels-like temp and a word for how it feels
• 8 digits: just the temperature and word
• 4 digits: just the word
