ESRack - Mounting Brackets

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, avilable in 3 sizes:
  • Short
  • Medium
  • Long
• Device Modules - each module can handle a single device

Possible 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 so installation of some devices may need to be pushed in by force.
Before you start printing the system, print the Connecting Block to check that you will be able to connect the modules.

I apologise that there are no detailed photos of the components after printing, but before assembly. It's because I decide to publish this project after fully assembling the racks.

All parts of ESRack system can be found here.

Part Description

Mounting Bracket is the basic element of the Rack System. It's universal and after rotating can be used on the left and right side to install assembled unit in the Rack.

Suggested Print Settings

Material: PLA+/PETG (I used eSun PLA+)
Nozzle: 0.4 mm
Layer height: 0.2 mm
Wall loops: 3
Bottom shell layers: 5
Top shell layers: 3
Infill: +25%
Infill pattern: Gyroid
Orientation: Print on front surface
Support: Not needed when correct orientation is used

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.
