Updated to version 2 in order to fix the drive rail STL.

For print settings and more information see the project web site.

Some notable points about this design from the web site:

• This is a rigid structure that does not flex much and when a fan is mounted it’s even stronger.
• The weight is distributed to the sides to prevent flexing.
• The drive rails distribute the weight to the sides across a wide cross-section in the strongest direction of the plastic. Less chance of the plastic layers separating over time.
• It is tool-less. No screws unless your PC case requires them. Not using screws also helps prevent the plastic from separating over time.
• This will fit in PC cases that use shelves for the 5.25″ slots.
• Active cooling directly attached via 120mm fan.
