About this 3D model

This is just a fast prototype I made inspired by the "deck hook" (http://www.deckhook.com/shop/deck-hook/). Im not even sure if i will continue this because my eboard is pretty heavy (~7kg) and realy anoying when dangeling arround my back. it holds fine but i didnt do any stress tests. Used 20mm doublesided velcro as straps. seem to hold just fine. Should work fine for normale skate / Longboards though
