QuickCuff VetMed Blood Pressure Cuff Holder

This is my attempt at making a better QuickCuff blood pressure cuff holder. I wanted it to hold up to size 6 and wanted a place for the cords to plug into so they could gbe slightly more organized. I also wanted the pegs to be angled upwards so that the cuffs don't fall off. Once again I am brand new to the modeling world so go easy on me and if you have any recommendations on how to make it better please let me know and I will try fixing the model.
