Here is the STL file. This is just a quick and dirty prototype, the
segments are not correctly aligned.
I got the idea from the franlab youtube channel, only 7 segments but really
nice design. You can also find some of this 3D printed segment displays on
Tinkercad.

Great idea with the 3D printer! Mammoth clock will ensue!

I would really like to get the cad and/or stl files. J

You can also use an HT16K33 chip which
Thanks for pointing out the HT16K33 issue with big displays!
I’m currently designing a self-made 16 segment display. The limit of my 3D
printer is 250mm (9.8”) but I will start with 140 x 100mm (5.5”). First, I
wanted to use a HT16K33. After your comment, I thought to use some mosfet

Hello,
Since you mentioned the Wemos D1 R2, why not use something like this….
https://www.ebay.com/itm/MAX7219-LED-Dot-matrix-8-Digit-Digital-Display-Tube-Control-Module-Arduino-ASS/264312125880
That’s what I use, and the cost is smaller than buying 2x 595 by itself.
You can cascade 8
