A small shelf to go on top of you shower door or glass surround rim in the bathroom.

I bet there is someone in your house that monopolizes most of the flat surfaces in the bathroom. Here's one for your stuff….maybe they can't easily reach. I've added different lengths of bolt to accommodate different. thicknesses of door and glass. I also added versions that have hex sockets if they need to be tightened more than you can tighten by hand. Delete whichever of the bolts you don't need and print it. It can accommodate glass or a door to 15mm thick. Because the threads on the shelf itself have to be printed horizontally, adaptive layers are used. If you're not going to use adaptive layers then turn on supports. A deburring tool will help you threading the bolt the first time ,but is not required.
