Wardrobe Hanger Extension

My 10yo daughter can't reach the coat hangers in her wardrobe and as I live in a rental I can't move the pole. I made these hooks to create extensions so that a new pole can be hung at a suitable height for her. I designed the round one first and realised I needed a heap of supports, whereas the square one only needs support in the two holes. Printed with 100% infill to give it strength. I also printed in PETG as that's what I do all my printing in.
