I never seem to have any luck with these kids of ball joint lids. This was printed with Creality PLA on a P1S. Waited for everything to cool down and tried to be gentle fitting the lid on because I recognize I have no luck with this kind of thing. however, still broke it! I love the design. I would recommend a tray that is a full verticle or horizontal length without separation to accommodate charger and screw driver. Otherwise, thanks for the design. Giving 5 stars because this might be a me problem.
