This project brings industrial-quality production to your kitchen table! In the industry, they call it desktop manufacturing.
At Sugru, we developed this unique rocking compression mould for the single most popular cable in the universe: the Apple Lightning to USB Cable. Now 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).
There are several options for getting your mits on your own 3D printed mould. You never need to own a 3D printer.
1: Order the parts printed directly from Shapeways.com. These guys print in an incredible range of materials and print resolutions, ideal if the surface finish is important to you. This does come at a cost though.
2: Order the parts from a local independent 3D printer through the very awesome 3DHubs.com. This is the fast budget option, we use this service all the time and love it.
3: Download this free open source file from the amazing ThingiVerse and get a friend to print it or bring it round to your local Hack Space.
- 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.
- 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 to set.
