I use an Anet A8, knowing that the tolerances might be off for your printers to keep the magazines in. I employ electrical tape and just friction fit it on. You could also use a piece of plastic and tape to put in the hole, which does line up with the magazine release hole. To make the BBS feed, I simply used a pen tube through the hole and super glued it in place. Additionally, you'll need to modify the magazines' base plate to get the BBSs to flow through easily. And finally, you must super glue the entire assembly together, securing it firmly to the magazine itself.
