The original design fitted my LCR T4 but it was not perfect. You still need to print the bottom case from the original design.

This is the one I ordered https://s.click.aliexpress.com/e/_DlLbzqD different vendors have different sizes, but it seems that there is only 2 alternatives.

Changes in my modded version:
-Screen bezel
-Button hole
-Back part
-SMD hole
-Slot for the lever

NOTE: The lower pin label is not right in the photo. It should be 123 1111 on both sides.
