I am absolutely delighted this is amazing!! I cut the belt a lil short first time round. One of the more popular x belt tensioners requires you have an inch or two extra so it wouldn't work for me. This fit in perfect, allowed me to secure it to the back of the extruder frame. Gave it a lil slack, then I begun to tighten it from the side. It now has a nice twang to the belt. After that secure in the screw that is in the side. It is perfectly rigid and works great!!
Thank you so much for this design!!
