Here is an alignment tool for Bambu's 3D effect sticker sheets. Using the tool allows for an easy bubble-free installation that is in the same sprit as Bambu alignment tool from the link below. The main different is in overall size and print time, as well, this uses a cam lobe locking system versus a threaded nut. It's fairly easy to use and can be illustrated in Bambu's video below. Be careful with the lock pin/dowel as it is printed in a weaker orientation and can be easily broken if there is too much bend applied to the part. However, it is a quick and easy print to replace it if you break it.
