No, but I have wondered the same thing. I only have a conturo due to space limitations so I wasnt sure if the diameter was the same. Although I had suspected it was. I dont see why it wouldnt work.
Does the Holzher cartridge fit in the conturo? Or does it need to be cut down to fit in the loading port of the conturo? Also what is the cost difference and is the holzher glue available in the same/more colors? Based on what I saw I dont know if there is any cost savings with the holher glue but if you want to run PUR glue it might be easier to source it in the holzher glue. Interested in knowing how it goes.
