Valentine Heart Message

myminifactory

For my valentine, I made a special gift. To view the message, simply pull the heart-shaped handle and let it retract back into its original position. This requires a 3/8 inch wide (9.525 mm) ribbon. My wife added a personal touch by printing text on heat transfer paper with an inkjet printer and ironing it onto the ribbon. You can see how the mechanism works in this video: https://www.youtube.com/watch?v=4G4Cmofq4Kk. To create this gift, I used computer-aided design software to print out the parts on my Ultimaker 3 Extended 3D printer using PLA material at a layer thickness of .1mm. I printed "Spring.stl" and "Back Enclosed.stl" with 100% infill, while printing the other parts with 20% infill. I purchased white ribbon and heat transfer paper, but also wrote some messages by hand on the ribbons using an indelible ink pen. To assemble it, I used cyanoacrylate glue to attach the ribbon to "Handle.stl" and "Spool.stl". The ribbon was placed in the 7 o'clock position on "Spool.stl".
