The Eurorack rails can be used to build your own modular synthesizer case. The rails keep your modules in place and have a lip to keep everything aligned. You need square nuts or a threaded strip to tighten your modules. A M5 machine screw can be used for fixation in the casing. These rails can also be found in Doepfer's cases.
