Step 1: 3d Print the Triggers
Begin by downloading the files below.
Note: This was designed for a phone with a thickness of .32'' (8.2mm) if your phone is a different thickness then you can edit them in a different CAD software using the files provided. Print with the flat side down (for best results) and the tab pointing up. Infill should be more than 60 % no supports needed.
Step 2: Measure Out Aluminum Foil
Cut approximately a half inch of aluminum foil off of a standard roll.
Step 3: Fold It in Half
Using a pair of tweezers (or just your hands) fold the rectangle in half length wise.
Step 4: Add Aluminum Foil to Trigger
Bend the aluminum foil around the small tab in a "u" shape.
Step 5: Apply Hot Glue
Apply a dab of hot glue on the inside of the tab.
Step 6: Insert Aluminum Foil
Quickly reinsert the aluminum foil back on the tab. Using a pair of tweezers compress the aluminum foil to the trigger.
Step 7: Apply Hot Glue (again)
This time put hot glue on the top of the tab and adhere the aluminum foil to it.
Step 8: Snip Off Excess Aluminum Foil
Trim the aluminum foil to your desired length.
Step 9: Make the Contact Pad
Bend the aluminum foil on the back side to make it flush with the top edge. Be careful, do not tear the aluminum foil!
Step 10: Apply Glue and Trim Off
Apply glue and push the aluminum foil onto the trigger, then snip off the excess.
Step 11: Repeat and Youre Done!
Do the same thing to the other one and your done!
Step 12: Video Tutorial
