After several attempts i finally came up with, what i think is the best sollution for a clean desk with all your components hidden away organized inside the drawer.

i've personally been used this design for most of my electronic components and it works great. Would recommend you trying it too:)

When printed all the parts you need 12 M3 screws, with the minimum length of 10mm. You must then connect the sidepanels to the drawers with the help of 12 nuts on the inside.
After tighten the nuts to the needed strength I would recommend using glue to temporary join the rails to the the mount. When that's done you can use 4-8 3mm screws to secure the drawer underneath your desk. if you would like to, you can visit my instagram to watch it in action, and see where all the parts go together https://www.instagram.com/p/CDjxsc4j4HB/https://www.instagram.com/p/CDjxsc4j4HB/

Tip! the drawer isn't made for heavy weight, especially on the lower ones. you can do as me and use the lightest stuff on the buttom and the heavier on the top.
