Check
Faceplate sits flush all round with no gap at the top edge; the screen aperture is square to the mount's top rail.
What you're looking at
mount.stl is the black printed carrier that holds the BTT Pi TFT4.3 touchscreen and fills the centre-front ring position. [a]_faceplate.stl is the blue bezel that trims the screen aperture. You build it at Ch 10 Step 10.50, before the ribbon is latched.
Caution
Rev D+ / LDO: you printed mount.stl (30 g, 44.8 mm tall), not mount_thick.stl (74 g, 67.8 mm). mount_thick exists only to give a pointy tool access to the screen's brightness buttons. If you find you want that access, reprint — LDO links the folder, not a file. src · print plan §6
