EDIT: Originally, I designed this to reduce the amount of VOCs circulating out of the chamber. At this time, I don't know how well it works for that purpose. It does help, however, keep the chamber warm when printing materials like ABS
The trap door is extremely thin, and requires a different material to support it. I used PLA for the print and PETG for the interface. I used super glue to glue the hinge together and double sided tape to mount it to my x1.
Looks to be compatible with most poop chute bins.
