When I printed the Tyrant trays and lids from the original designer, I found them to be too loose as they slid open on their own if the tray was tilted. This could very well be due to discrepancies in printer profiles and calibrations. Nevertheless, I remixed the lid to be 0.4mm longer and now I have a nice friction fit.
The original designer uploaded SCAD files for easy modification, but I realize editing those might not be within everyone's comfort zone so I am posting a model of what works for me.
Thanks again to the original designer for sharing their hard work.
