A stand for the RCS-18X-0 but it might fit other models and brands (the base is 150x315mm). The pegbord mounting is for CC12mm. There is space for the fence in the back of the holder to maybe not lose it to fast. 

There is one split model if you dont have your XL yet and one and one complete model.
I have used CNC kitchens M4 insets in the front and a miter-plate to stiffen the front for the split version, it could also be glued if you dont have the inserts.  

I would recommend printing it in PETG or tougher material. A 20mm brim made the parts not warp for me.

If you need it modified let me know or I will add the file for fusion360
