@Jain Drilling the tiles isn't even hard. Just do it slow without the punching/hitting function enabled.
It's just I'm a silly kitty who lacked patience and drilled all willy nilly at 3am without bothering to waterproof the holes at all :blobcatgiggle2: Oh and I didn't measure so I did 3 holes only to realize they didn't align and just install the arm using 2 screws :ablobcat3dverified:

At that place I also painted all the walls black so :blobcatlaugh2: The landlords fear me.

I'm trying to tune back the terror nowadays lol
