The 'Linkable Chain Bracelet' is just two small parts that join together... multiply to create a chain or bracelet that you can link to make it endless. Once fitted it won't come off unless you want it to by reveing the final linking process. The parts are small (so quick and easy to print) and don't use much filament. Print in a range of colo so you can make up your own unique combinatio of color schemes. Great fun fashion or wear them in your favourite teams colo or to suit a theme or event. Itructio for assembly is provided in the images. Once you know how assembly is easy... but the final linking is a bit fiddly on your own. Having someone link it for you is the easy way but, to make it readily 'do-able' by youelf, a Linking Tool file has also been provided. It's another small part that you only need one of... it's function is to hold the joiner in place while you link the ends of the bracelet / chain. This is a really simple and fun way to make a colourful wearable 3D print. However, please read the additional information provided and the images as this provides itructio on assembly and linking. An average wrist requires 12 or 13 of each part to create a bracelet. Please post images of your bracelets and chai for other membe to see.
