Adjustable router template. Easy to print, but it takes some time. If the size(limited by the print height of the X1C) is not enough you can print additional profiles and extend the length or width.

To put it together you will need heated inserts, 2 for connecting sliders and 2 for the profile if you want extend it.

For fastenners I advice M4 button head 18mm screw. You can use different type but then you will need use some washers as wel. Also they need to be operated with allen key. There is no space for screwdriver.

The round block is to support router. Fits on my Festool OF1010. You can use it when you unscrew one of the screws holding the router plate. Then you fix it with M4 button head 18mm. It may fit other routers as well as long as they have M4 hole at the bottom plate.
