This is my first design upload.

I got asked by friends to design something to hide their dog's flea and tick collar underneath their fancy designer collars.   I have version one on my own dog, which I haven't bothered uploading because it is square and not particularly sleek.  This oval-shaped one is designed for collars ~20mm wide.  I have printed in PETG to hopefully give a little longevity.  Multiple clips are placed around the collar and the flea collar to keep the flea collar in contact with the coat, but hidden.  Some adjustment of collar lengths is probably required. 

Thank you to Penny for modelling.
