I always struggled to measure the position of the rail and keep it steady during cut. This simple jig allows to just put board in and cut, always straight always 90° to sides.
The rail is hold by magnets 6x3mm in place, 24 for one side.
The magnets in the rail are flush with bottom so they are designed to stay in there.
The profile base part is designed to be milled in the side. It thickness is 3,5mm.
It is very easy to take the rail off and use anywhere else and then just CLICK! on place and cut in the jig.
No special requirements for printing. Use whatever you like. I used PLA, 0,25mm, 10% infill, 3 parameters 3 top 3 bottom.
