Rack rails M5

This is a rail kit for rack mounting of computer or music components or devices. Designed for use with M5 screws and nuts. There is currently a 1U, 2U and 4U model so that it can be printed with most printers. But more can be done by modifying the".f3d" file.

New: Variants of the 1U model are available to adapt to different types of screws (milled head and cylindrical head).

A technical data sheet is available in PDF format, containing all the dimensions required for installation.
I was inspired by this thing: https://www.thingiverse.com/thing:2105966
Because it does not use the metric system and it was not adapted to my use.
For the dimensions I based myself on the Adam Hall 61535b6 so you can replace the 3D printed model with Adam Hall's metal rails.
