4x magnifier LED display

thingiverse

This device expands the area of the LED matrix by 4 times. My goal is to utilize an expanding light separator. If you print it from a translucent material (and my silver plastic turned out to be slightly translucent), then the image elements become "voluminous", and, for example, if you use the firmware to display the clock, the numbers will also be three-dimensional. However, you can print them in black plastic and get a classic scoreboard, but 4 times larger at a lower cost. All the electronics will amount to about $7. Depending on the firmware, you can use this device as a clock, lamp, creeping line, night light or color music display. The design does not employ filling, but only walls, making printing relatively fast and low in material consumption. Additionally, no screws or other fixing methods are used. You can see how it works by watching the video at https://youtu.be/O-WCk1mXSQI. UPD I added a version with two-sided frames, its printing is one-third faster when corners closed by cooling from a fan are not created. This option has not been tested yet, but I think it's better to print it from more rigid PLA.
