For Valentines day, I made a heart NFC keychain tag, that can be used for love messages, favorite songs, addresses etc etc. You can use the file for your own use, but can't be used to sell. Neither the file nor the heart NFC keychain can't be used for commercial use.
Insert a heart shape from XCS.
Add another heart and make it a bit bigger then the first one and copy that one 2 times.
Insert a circle and set it to 1.1 inch. Place it in the middle of the heart, so it has a tiny bit of space on all sides.
Adjust the heart size, so the circle fits right in. Remove the circle and group the inner and outer heart.
Use the 2nd copied heart and make it the size of the first heart. You can overlap it with the first heart, to make them even, or check the measurement of the first heart, to get the same size. Insert a circle and place it right in the middle of the heart, with a little bit of overlapping. Click combine and the circle is now attached to the heart.
Add another circle and make it small, so it fits in the first circle then group it.
Now you have an open heart with a hole for the loop.
The 2nd heart will be the bottom and the 3rd heart will be the top.
I engraved the words Love on one of the hearts, that will be the top.
Use acrylic glue or whichever glue that sticks acrylic together and place the open heart on the bottom heart and glue it together.
Place the NFC tag in the middle and glue the top heart on the open heart.
Use a hoop ring to go into the hole and add a key ring.
Now the Heart NFC keychain is finished.
