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 http://www.ebay.com/itm/172326351345 different vendors have different sizes, but it seems that there is only 2 alternatives.
Changes in my modded version:
-Slot for the lever
NOTE: The lower pin label is not right in the photo. It should be 123 1111 on both sides.
