Raspberry Pi Server Mark III

Raspberry Pi Server Mark III – Uptime Lab

Raspberry Pi Rack Server Mark I и Mark II have been working pretty nice for 6 month already. Both of them are based on a model which I found on thingiverse.com and inherited the basic design idea.

With Mark III, I completely rethought the design, which allowed to:

• increase the number of raspberries by 2 units
• significantly reduce printing time and plastic consumption
• significantly reduce the time required for assembling and disassembling the server
• reduce the number of parts
• implement a modular design, which means that MARK III will be available in various modifications

I’m glad to present the first basic model, designed for 14x of Raspberry Pi and 14x of a standard 2.5″ SSD.

Printing recommendations:

• layer height 0.15mm
• wall thickness  0.6mm
• no supports
• horizontal expansion  -0.1mm
• without a skirt  

Please print one Tray and one Body part first and have a look at how they fit each other, as well as how it works with Raspberry Pi and your SSD.
