About this 3D model

Concept: A ring box where the ring moves in a helical motion when opened. No hardware needed. There are two versions: One with a heart able to lock on a ring One with a flat heart, where you can engrave your desired text. This model was designed for the Saint Valentin's contest. You can find the ring here https://makerworld.com/en/models/182128#profileId-200649 Print files: The included 3mf should work absolutely fine with Bambu Lab printers. There are two plates: One with the case ( base & lid ), the top cover , sliding tray and two clips . I printed this plate in overture wood PLA One with the helical heart with its guide (printed in place) and the slider (locking the ring). I printed this plate in red eSUN PLA+ Assembly: The heart and the guide are “print in place”. Twist the guide to break it loose. (it should revolve freely inside the heart ) Pressfit the guide onto the sliding tray (look for a dent in the tray) The lid has two pins which must slide into slots in the tray . You must now have an assembly with heart , guide , tray and lid Insert this assembly into the base . Note : Make sure the heart is initially inserted facing you. It will twist and face away when it goes down. Insert both clips to secure the lid . Install the cover to hide the mechanism. It pressfits on the base . Install the ring and lock it in place with the slider Note if you want to slice the files yourself: To minimize friction, the base and tray must be printed in an orientation leading to layer lines being orthogonal. If you print the tray flat, the print lines will be parallel which rub. Avoid printing the lid flat on the bed. The lid “legs” could be too fragile. As there is tight tolerances (to allow smooth sliding) please use (“outer/inner” wall order). I recommend enforcing support for the pins of the lid. I am cleaning up my source files, and I will post the link soon. (I designed everything on Onshape). If you are interested, please leave a like J
