Well, if your a parent of a young child with bunk beds then you know the middle of night call “DAD, I CAN'T FIND MY WATER". Which you have to come in and dig through the blankets and corners of the bed to find said water bottle. Well it began to get to me, so I had to do a little thinking.

This cup holder latches on to the bed rail to holder to hold a cup or drink container in place for easy access, to keep it out of the bed and avoid any potential leaks when its not closed properly.

The inside of the hooking mechanism will fit rails up to 19MM which may need to be remixed to fit your child's bed. I will be adding little silicon stickers to mine to stop my child from sliding it all over the rail. The guide hole supports bottles, cups or anything up to a diameter of 77MM. Overall from top to bottom the design is 110mm and the bottom base plate is 90MMx90MM.

I printed this first model in PLA with 15% infill to test it with minimal tree supports to support the circle cut out. Its plenty sturdy but if your child is rough and tumble than PETG would be a superior alternative.

Enjoy and happy water bottle searching…
