A resin rail developed with low cost in mind. Modules are screwed into a nylon bar inserted in the rail; the rail body and the bar that takes the screws are separate parts.
The base lineup covers 3U/7U, 40HP/60HP and black/white. 7U is 3U × 2 rows + 1U. This is version 2 of the rail, finished after many rounds of refining the parts, the rail shape and the set contents while building cases.

Material and colour
The rail consists of an outer part and an inner part. The outer part comes in two materials, white or black, both resin. White is cheaper but may yellow over time; black costs more but has a nicer finish.
Both are about equally durable. The material is hard, but please be aware that a strong impact can crack it. Compared with metal, it will crack if you bang it hard against a desk, but it is plenty strong enough to carry a case full of modules.
Nylon screw bar
The inner part is a long nylon bar with many holes for M3 screws, equivalent to what is often called a "bar nut" in modular synth cases. It is the result of quite a bit of trial and error.
Most rails take screws in metal, but this one uses nylon, a type of plastic. Driving a screw takes a little more force on the screwdriver: the holes are slightly smaller than a standard M3 screw, so the screw bites into the soft resin and seats itself. The downside is that mounting and unmounting a module many times wears the holes.
Why build it this way? To keep the price low. Version 1 was made on a home 3D printer; we tried many approaches then too, and its durability was far lower than this version 2. Even so, the version people bought most was the cheapest one. An affordable case is what most people need to start with modular synths, and we think a rail like this is a good option for that.
You might think "but it's plastic…". We tested many materials that suit this bar and fit the price, and arrived at this one. It is not as strong as metal threads, but we think you will find it works surprisingly well — we'd especially recommend it if you are considering building your own case.
Besides this nylon rail, a metal-nut version is also in the lineup — please take a look at it too.
3D preview
Switch the height, width, mounting method and rail colour, and see the rail assembled and taken apart, including the screws that hold the rail and the parts inside it. Colours and surface finish differ from the real product. The viewer's labels are in Japanese.
