This project brings industrial-quality production to your kitchen table! In the industry, they call it desktop manufacturing.
We developed a compression mould for the single most popular cable in the universe: the Apple Lightning to USB Cable. So you too can experiment with this exciting technology.
Whether it’s just for kicks or to start a bustling cable repair business, professional moulding is easier than you think.
All you need to create industrial-quality strain relief for your cable is a 3D printed mould, a pack of Sugru, a paintbrush and some dish soap (washing up liquid).
Download the 3D file for free from MakerBot's Thingiverse, the world's largest 3D printing community, print it at home or find your local 3D printer at 3D Hubs (www.3dhubs.com).
Paint your mould with a light coat of soapy water (that’s just a drop of dish soap in water) and shake off the excess.
Use half a pack of Sugru - roll it into a long sausage roughly the length of the mould. Press the Sugru flat and then wrap the Sugru around the cable and press it into a rough shape making sure that there is more near the connector end of the cable.
Place the cable into the mould and then put the top of the mould on.
Press the two parts of the mould together and rock from side to side. The crete the mould form and pushes the excess Sugru out - in professional compression moulding this is called flash.
List off the top of the mould and trim the flash (excess Sugru) off.
Apply more soapy water to the mould and repeat the moulding and trimming process.
Leave the Sugru to cure and after 24 hours it will turn into strong and flexible rubber!
