Double Sided Shower Hook

Thanks to Marcmex for his hook https://www.thingiverse.com/thing:4117588. I was looking for something like this to put on my shower stall to hold a towel outside and a washcloth inside. I just mirrored the hook and merged it. My shower wall is slightly curved and it fit perfectly, so you may need to tinker with the stl to get the gap to the correct width. Enjoy.
