Octorack - Fully 3D Printable Network Rack (Zero hardwarde required)

Octo Rack is a fully 3D printable network rack, that can be clicked together. It requires no heat inserts or screws to assemble (the only exception being if you want to wall-mount the rack).

The versions uploaded so far have an internal rack depth of 150mm, and can be assembled in two widths:

• 175mm useable width - this enables the top and bottom panels, and any internal modules to be prnted in one piece on a printer with a build plate bigger that 220mm x 220mm.
• 222.25mm - this matches the internal space between the rails on a standard 10-inch rack (see https://commons.wikimedia.org/wiki/File:19_inch_vs_10_inch_correct_rack_dimensions.svg)

The octo rack is built around two “Core Components” - the mount and plug.

Core Components

The core dimensions are a 20mm square unit, with a 16mm internal diameter octagon hole. 

The plug has a 0.15mm tolerance all around to enable it to fit inside while still being a tight fit, and has four tabs that engage into a inset within the mount hole.

The mount is designed so that the plug can be inserted from either side, which is used when wall-mounting the frame, or for rear-supports for the modules (see later)

How to assemble your own rack

To build your own rack you will need:

• 4 rails (I've uploaded four different lengths to choose from)
• 2 Side Panels - make sure you pick the right size to match your rail size. Current versions of the panels are either solid, vented, or have a large hole to enable cable entry
• A bottom panel - again solid, vented or cable entry versions are available

Depending on how you want the rack to sit, will then determine the other parts you need:

If sat on a surface:

• A top panel 
• 4 feet - these can be found in the Misc folder

If you are wall mounting this from the rear:

• A top panel
• Either one or two full-width mount, depending on the weight of the rack (there are also individual screw plugs available, however the full-width mount has the built in rear supports, so is preferable

If mounting to the ceiling

• 2 full width mounts, or 
• 4 screw plugs

Inserts/Modules

As part of this model, I have uploaded some basic, starter components. Each component comes in the two widths mentioned in the introduction, as well as in two aesthetic versions, with hollow plug centres, or solid.

The components uploaded are:

• Blanking plates in two heights
• Shelves in two heights
• Cable passthrough plate

Enjoy, and let me know your feedback!
