Make Linear Rail
Linear rail consists of a thin aluminum angle held by several rail supports mounted on perforated angle of the same length.
Linear rail comes in several lengths: 6", 12", 18", 24" etc. A pair of rails and at least a pair of linear bearings are needed to make a complete linear stage.

- Thingiverse: todo
Saw the necessary length of the thin aluminum angle.
- Pre-fabricated rail supports will be available for purchase separately from a kit.
- Rail supports can be 3D printed (needs testing)
- DIY rail supports are made from standard aluminum bar 1"x1/8". Make them from SVG templates, according to the instructions in Howto section. To mark the holes in the bar for 6-32 screws, clamp the bar with an angle piece in a vise as shown (pic__) and use 3/16" dia transfer punch touching the inner wall of the angle when punching. This will ensure that the holes are accurate. Todo: add pictures.
