Remixed the tabs so it has a pin to hold the spring for easier assembly.

• Use supports under tabs.
• Use along with original body and lid here.
• Insert spring into pins, compress spring with tabs and place into lens cap body.
• Use a bit of glue on the sides, put on the lid top onto the body and hold for about a minute.
• I waited a full day for glue to cure before trying on my camera.
• Push tabs together to free tabs since glue will sometimes get in the tab area, you might need to do this a few times.
