I designed this to replace the original latch of the case for my SKIL electric screwdriver (SD561204). This is an exact fit replacement which is tighter so it doesn't wiggle around. It's not a necessary replacement as the original latch works fine, I just wanted it to be tighter for two reasons: lid will stay tightly closed in the locked position, and is easier with a little knob on it. I personally used PLA (for color) when printing but you may want it to be in PETG for extra strength and durability.

Simply open the case, slide the old latch to the left to remove, and repeat steps in reverse to install the new one. May be a little tight at first but should move smoothly with a little bit of use.
