3d printed Handy adapter for a SVAKOM Alex Neo Sleeve

I hate the Handy sleaves. I hate the way Handy holds the sleeves. When I tighten down the sleeve it becomes too tight for me. If I make it looser, it comes out. Very irritating. So I have been 3D printing hard sleeves with twist patterns in them. But recently I decided to design an adapter to hold my Alex Neo Sleeve in the Handy. It works great and I am very happy.
