Print your own desktop manufacturing kit to produce precision rubber parts directly onto the iPhone 4/4S or iPhone 5 with sugru.

There are 2 sets of molds here: 1 set for the iPhone 4/4S and another set for the iPhone 5. Each set has 3 components (make sure you print them all)

You will also need a set of nuts and bolts:
Metric: 8 x M5 x 25mm bolts + washers and wing nuts.
Imperial: 8 x 10/32 x 1" bolts + washers and wing nuts.

UPDATE - 17th May - We've just uploaded a new set of molds with an improved draft angle for better release. Please download, edit and create the molds as you wish.

If you think you can push this technique further, we're giving free sugru to the very best ideas.

What exactly does this thing do??

Hello Eric. This is a compression mould design that allows you to produce precision rubber bumpers on the iPhone 4 and 4S. If you watch the video you should see how it works. Hope this helps. James

UPDATE 17th May - We've just uploaded a new set of molds with an improved draft angle for better release. If you've downloaded the previous version, let us know how you've got and how you think we can improve.

Keep up the good work, Sugru! :-)

Even better, don't use Sugru (because it's expensive) and instead use "Oogoo" - it's a mixture of silicone caulk + corn starch. The corn starch impressively speeds up curing time of the silicone and makes a perfect substitute for Sugru
