Print & Build Guide

I've tried to keep the assembly process as easy as possible but depending on printer accuracy there may be slight fitment issues. Some parts may require supports. Tested with Overture PLA Professional.

Note: The middle piece is bigger than the individual rack units. This is due to the fact that a Kallax cube cannot easily be exactly divided into 1U segments.

Frame

Tray

The tray_pin.stl file holds one half of a pin design. Print four copies to produce two complete pins. No glue is required. Simply insert each pair into their designated holes.

The trays are designed to be interchangeable. You can combine different models for each side.

Example: nuc_tray_1.stl + pi_tray_2.stl

The assembled project should look something like this:

Below are the measurements that you can use to design your own rack inserts.

Middle

This was my first "big" 3D design project. I am still learning and getting better. If you face any issues during printing or assembly, please let me know and I will try to help.

This project has taken a lot of time and effort. If you find it useful and want to support me, please write a comment and post a make. It would mean a lot to me! :)
