‘Tis the season for hot chocolate, snuggling close to the fire, and of course festive holiday sweaters!

But being the best dressed during the holiday season doesn’t just end with the knitwear you pull out of the back of your closet once a year.

This year, extend your festive fashion to your best accessory. Now you can “knit” your phone its own seasonal sweater with the 3Doodler Start, a 3D printing pen that’s safe to use on electronics because it has no exposed hot parts. And the specially engineered Eco-Plastic is not only environmentally friendly, but won’t stick to or ruin your phone!

These phone cases are designed in the style of traditional Fair Isle knitting patterns, so they’ll fit right in with you festive cold-weather clothing!

All you need is the 3Doodler Start, some of the Eco-Plastic in holiday colors, and your phone.

And if you don’t know where to start or don’t want to go through the trouble of making your own pattern, 3Doodler helpfully offers 5 patterns ready to print and sized to fit your phone!

Because it has no exposed heating elements, the 3Doodler Start is totally safe to use on your electronics. So you can create a 3D printed, free-hand phone case customized to fit your phone perfectly.
