For those fans of photography, there is a camera available that can be 3D printed at home on your FDM based 3D printers. It's called the OpenReflex camera and the founder is currently running a crowdfunding campaign on KissKissBankBank in order to raise funds to advance it further. The instructions on how to make it can be found on instructables, and the files can be found on Thingiverse.
