This is a model that we made to lift up the reality lid does two things we're able to get air flow with the door closed so it keeps the chamber cooler with PLA and pet G as we've noticed that it's been rising up quite a bit even with the back fans on and the exhaust fans but also the PTFE tube has a bit more room at the top doesn't rub on the glass so theoretically easier flow of material to the hot end it has two side stationary pieces two slider side pieces two front and rear pieces stationary and sliders then we have four corners on this I have printed this in as a material as this material is going to withstand the heat it did it like a boss on the bed we have no issues whatsoever please let me know what you think in the comments if you'd like any modifications done to this as I feel like it's worked straight away you can glue it together if needed at the end but the pieces should be a push fit.
