Extension parts and alignment notch mod for Split-Flap Display

These modded parts allow you to add as many more Units/Characters to your Split-Flap display as you want – as well as align the units better using an alignment “notch” for each character. Extending the Display Center2 and Center3 contain replacemens for the center parts of the case to extend it by 1 or 2 characters. Extend1, Extend2, Extend3 and Extend4 contain additional parts that can be added between the respective center and right parts of the case to extend it by 1, 2, 3 or 4 characters. Improved Alignment I noticed that the UnitFrame parts can bend a bit when the nuts are inserted. This is not a big issue and doesn't affect functionality, usually. However, it means the letters aren't perfectly centered in their respective windows. I added alignment notches to remedy this issue. To use them, use the FrontCoverWithNotch and UnitFrameWithNotch parts. I provide the Center and Extend parts without an alignment notch as well, so you can use them with the original UnitFrame part if you prefer to. Improved PCB I also made a improved drop-in replacement for the PCB, which you can find here: https://github.com/codingcatgirl/split-flap-fae-pcb Other mods i recommend If you haven't stumbled over them already, i recommend you also look at these two mods: https://www.printables.com/de/model/684223-split-flap-drum-magnet-increased-tolerance – I found this one necessary to be able to mount the magnets when printing the drums on my Prusa MK4. https://www.printables.com/de/model/689270-split-flap-display-usb-type-c-power – If you want your display to be USB-PD powered.
