About this 3D model

I created a back plate with a hanger. People told me that a lot of the clockworks don't come with an hanger. I came up with an solution if you printed the clock and have no hanger. just slide the back onto the clock. It schould hold by itself, if not use some glue. The clock is still be accesable. Have fun printing. Here you find the clock faces. https://makerworld.com/en/u/2111078438/collections/175507 Boost Me
