Dry box spool holder

This is just a simple holder that I designed to hold the rod that supports the spool in my filament dry box. My box is of a similar design to that in CNC Kitchens design (https://www.youtube.com/watch?v=WEFtUKGAd7k) but I used a bamboo rod so it is much narrower.

I hot glued it to the inside of the box instead of bolting also.
