Secret Heart Locket
thingiverse
Update: I added a smaller locket (files labeled "small") with tighter tolerances for better machines than my Anet A8. Happy Valentine's Day! I came across a "Secret Heart Photo Locket" made from popsicle sticks. It was really cool, but looked super cheap. I designed this initially as a pattern to machine out of brass, but I ended up making it printable too. https://www.youtube.com/watch?v=Q1LqD53ROL4 You'll need to print (2) Outer parts and the two Inner parts. I've included the STEP file so you can adjust the tolerances for your machine using the User Parameter "tolerance".
With this file you will be able to print Secret Heart Locket with your 3D printer. Click on the button and save the file on your computer to work, edit or customize your design. You can also find more 3D designs for printers on Secret Heart Locket.
