IVL2 VFD WiFi desk clock

After the classic IV18 VFD tube clock published one month ago https://www.thingiverse.com/thing:3417955, here is a less known tube: the IVL2-7/5 Vacuum Fluorescent Display Une première on Thingiverse ;-) The display includes 4 digits and two dots. It is a flat tube with lateral pins. All the needed pins are present at the bottom of the tube (segments, digits, filament) while the digit and filament pins are duplicated on the other side of the tube. At one end the tube shown a weird small queuzot from which the vacuum is applied during manufacturing. This is a very fragile part that must be protected. I wanted an as light as possible housing for the clock in order to keep the inner of the tube and is transparency fully visible. I ended with this design which is very easy to print (only two parts) and into which all the electronics can be hidden. As for my other clock: - it is self synchronized via NTP over WiFi using a simple ESP8266 to perform all the job. - there is no dedicated PCB - everything can be bought from ebay for around $20 - an automatic presence detection allows to switch off the filament when nobody is watching the clock. see it on youtube : https://youtu.be/o4gyktB0RMc
