Vertical key holder

Hi everyone This is my first creation. A simple, vertical key holder with 4 key holding slots (pictures show a 5 slot version, but I reduced to 4 for this model). Just wanted to be able to hang keys vertically, due to lack of horizontal space. I have printed using both, PLA and PETG. 25% infill, just to give a little extra strength. Hope others find it useful too.
