Layer Height: 0.2
Support : Yes
Support Style : Tree Slim
On build plate only : Yes
Remove small overhangs : No (Otherwise the top of the sliding door track will collapse)

*Please be careful when cleaning the door support, it is easy to tear.
The connector is not necessary. If you need it, you can download it here.
