Please note this model is for the original microlab linked below, not for my parametric version. 

Microlab Module Templates

To make it easier to design modules for the Microlab by CB4D, I created a parametric module template that you can download and open in Fusion 360. I have also uploaded STEP files for modules with a 1U, 2U, 3U, 4U and 5U front panel. Each of these STEP files has a 100mm tray depth. For further customization please make use of the Fusion 360 F3D file. 

Customization

The F3D and STEP files I have included can be found by clicking on the arrow next to 'Open in Bambu Studio" and then selecting “Download STL/CAD Files”

In the file I have favorited two parameters that you can change to quickly customize the template

Access via [Modify > Change Parameters]

UNumber - The height of the front panel in U. (1U = 22.5 mm) 

TrayDepth - The depth of the tray that goes horizontally backward into the microlab (absolute max for this would be about 150mm to still fit within the microlab, but you should do shorter if you need to run any wires down the back.

This gif illustrates how I go from a 2U template to the module I made for the Netgear GS305E Ethernet Switch

This model can be found at the link above, but here is the printed end result mounted in stock microlab parts. 

Thanks to CB4D  for publishing the original microlab, I may be inspired to make my own fully parametric version in the near future!
