Designed this for my daughter to lessen the middle of the night wake ups to reach water or find her chapstick lol :) 

Printed this using Elegoo Wood PLA with no issues. The orientation of the print does make the “top” side of the big hole come out a bit rough even with supports but it's not too bad, could be improved with some tweaking i'm sure but I didn't need it. 

The width of the bed wall was 18.5mm and the cup hole was 95mm, if yours is different, you'll need to change it. For this I added extra photos (all the _tinkercad.png files) of the tinkercad design with all the parts and their dimensions so that you can recreate them if you want. One day I'll upgrade to fusion or freecad but for now, i'm comfortable with tinkercad.
