40cm (around 16 inch) server rack.

There are many great 10inch racks on internet but i needed something bigger for my hp elite desk g3 sff so i created this large rack (im still working on it. Its my first time modeling something bigger and more parts complex).

This design uses only m3 screw nuts and heat set inserts.
I modeled it so every 1cm from center there is another screw hole (hope that wont turn out too weak).
At the moment only the main rails and the basic connectors were modeled but its enough to build it.

In Future if the construction wont be able to hold up the weight of the pc there will be tensioning strings and stuff but we will see.
