I don't have the q-snap frame but my husband made me one out of PVC pipe which is real close to the q snap frame. It all comes apart and takes up no room to store it. I have seen them at Hancocks fabric store I can't remember the price but maybe you could get one made. I use mine all the time for hand quilting and then I machine quilt the borders.
Let me know if you want any more info I think they sell them on the internet through some web sites maybe you could get the measurements from that and have one made.
