Guide Rail Parallel Stop for Festool

his jig replaces Festool's FS-PA (Parallelanschlag), which is quite expensive and large (I have a small workshop). It is the simplest solution I could come up with that offers highly precise repeatability for multiple same width cuts. It allows same-width cuts at any width, limited only by the length of the rods that are used (Festool's jig is limited to 650mm).

The parallel stops are attachments for the guide rail and can be attached on both sides. They are optimised for small cuts, i.e., for the front side of the rails, because I found myself in more need to do this precisely.

The jig does not attempt to incorporate any way of measuring. Calipers and measuring tape should be available anyway. The main goal of this jig is exact repeatability. The jig does offer very good precision of front side cuts measured with calipers, however.

An introduction to using this can be found in his blog: http://www.theiling.de/cnc/date/2019-04-14.html

Bolts and Nuts
The following parts are needed in addition to the printed parts. These are all metric (I live in the metric part of the world).
6 x M5x35 hex head screw, DIN933 (or DIN931); longer ones work, too, I used M5x40
2 x M5x50 hex head screw, DIN933 (or DIN931); longer ones work, too
8 x M5 large washer, DIN9021
8 x M5 hex nut, DIN934
2 x ca. 400mm (or longer) of 10mm round tube or rod (brass or aluminium or steel or plastic); M10 threaded rods may work, too, but as they bite into the plastic, they might harm precision and might wear out the plastic parts.
The rods should be at least 400mm so that cut at the front side of the rails can be made that are wider than ~200mm, at which point the rail can be turned around to make back side cuts. For back side cuts, the cut width is limited only by the length of the rods: if you need longer cuts, just get longer rods.
