Yeti Lid and Magslider organizer
I saw a post on a yeti Facebook group of something similar a guy was selling that inspired me to design and print my own with a few improvements.
Most versions of tumbler lid organizers that i've seen are designed such that unless you were constantly reorganizing everything you just ended up using the same 2-3 lids in the front all the time. This version allows for lids and magsliders to go into the top and be pulled out of the bottom ensuring all the lids get used in rotation.
This design is specifically for the medium 20oz/ 10oz lowball lid. Holds 8 lids and 6-8 Magsliders.
I don’t have the time or energy to try and sell these so I posted it up on thingiverse for anyone interested in printing their own. Happy to send the CAD file in step format to anyone interested in making further improvements or design changes of their own.
