As you may know, Finland's Jolla finally launched its first smartphone on the 27th of November in Helsinki. Jolla was founded by a group of ex-Nokia employees before then-CEO Stephen Elop decided the firm should switch to Windows Phone as its high-end platform. They believed the Linux-based MeeGo deserved a second chance. The device uses an operating system called Sailfish OS, a modified Megoo Linux system from Intel and Nokia.

MiniFactory, a Finnish 3D printer maker has created the first 3D printed jolla smartphone cover. They write:

Few days after jolla released their smartphones, a guy named Jani Pärnänen contacted us (miniFactory Oy Ltd) with the idea that we should create a 3D printable cover for Finnish jolla smartphone and print it with Finnish miniFactory 3D printer. We decided to help Jani with his idea and invited him to our office.

After Jani arrived we went quickly through the new jolla phone which was really interesting new smartphone. After the walkthrough of the jolla we started to design the new 3D printable cover.

First prototypes were printed after few hours of designing to make sure the cover fits perfectly. The hardest part of the design was to find a good design around the buttons so they could be easily pressed and the cover would protect them. A few more details was made like few cutouts on the cover sides to make swiping easier, endstops on both ends of the cover, a hole for a camera, for a flash and for the nice jolla logo.

It took 7~8 meters of ABS filament and a bit over 2 hours to print this cover on a MiniFactory 3 Education Edition 3D printer. Check out the photos below: (The plan can be downloaded from Thingiverse)

For those who don't know yet, the MiniFactory manufactures entry-level FDM 3D printers and launched its first 3D printer in Nov. 2012. The current version, miniFactory 3 is designed for the education market, which features metal frame design, high quality noise insulations, and 15x15x15 cm build envelope. Compared to the earlier prototype, the most important enhancements are the optimized nozzle structure, better mechanical motion and item coolant solutions. Most 3D printers mount the extruder assembly on fixed plane, and move it left and right to create the X-axis of a 3D print. The MiniFactory 3D printer has a moving print bed instead, and this mechanical motion ensures the printing material to be directed into the right spot.
