I love 3D printing.
Out of all the tech hype cycles and trends over the last decade, this one is genuinely useful.
There’s simply something magical about being able to design or download a model from the internet, send it to a machine,
and after a few hours you get an actual...

The Microserver Gen8 has nice features such as:
