Guide Rail Parallel Stop for Festool

This 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 my blog: http://www.theiling.de/cnc/date/2019-04-14.html

The STL files come in two variants: those in '-2.stl' are rendered using OpenSCAD. They are precise and small, but take long to generate. Those without '-2' in their name are rendered and pre-sliced for 0.2mm layer height using Hob3l. The process of creating these takes only seconds, but the files are specialised for a given layer height and are typically larger.
