I designed this solution when my keychain D-ring broke during the holidays, and purchasing a replacement was not feasible. I dedicated 20 minutes to create this simple design, which I have successfully printed approximately five times. The functionality is as follows: print the final component, insert your keychain lanyard through the loop, and then secure it. Once locked in, thread the keychain ring onto the larger loop, and you will have a fully functional keychain D-ring. Please refer to the accompanying images for a visual representation of the fully assembled item. Additionally, during the printing process, you can attach the metal portion of the keychain ring to the print once the loop is approximately halfway complete.
