ESRack - Module - Apple Mac Mini 2012

Introduction

When I decided to assemble my HomeLab Rack I wanted each device to have its own dedicated holder, as I like to keep everything tidy and wanted to avoid a mass of shelves. Unfortunately I couldn't find any satisfactory solution, so I decided to design my own modular solution that would allow multiple configurations.

The ESRack system includes components:

• Mounting Brackets - used to install unit in the rack, available in 3 sizes:

  • Short

  • Medium

  • Long

• Device Modules - each module can handle a single device

The original ESRack system was designed for 19-inch racks and allows multiple configurations:

- [Mounting Bracket Short] + [Module] + [Module] + [Mounting Bracket Short]
- [Mounting Bracket Medium] + [Module] + [Mounting Bracket Medium]
- [Mounting Bracket Short] + [Module] + [Mounting Bracket Long]
- [Mounting Bracket Long] + [Module] + [Mounting Bracket Short]
- [Mounting Bracket Long] + [Mounting Bracket Long] (Blank Front Plate)

All modules were designed with very little clearance to keep the whole assembly rigid and properly fitted. Some parts may need to be pushed together by force during assembly.

Before you start printing the original 19-inch system, print the Connecting Block to check that you will be able to connect the modules.

The ESRack system also supports 10-inch racks using dedicated adapter.

All parts of ESRack system can be found here.

High infill is needed to avoid bending after installing equipment. I used 20% infill and with heavy equipment it's bend a bit.

Assembling

To connect the each individual modules together, you need:
- 4x M4 nuts (DIN934M4)
- 4x M4x12 allen screws (DIN912M4x12-8.8)

Use standard rack screws and nuts for rack mounting.
