Neptune 4 Max build plate alignment tab with attachment for the cable chain

My Max has very small gap between auxilliary fan and build plate when gantry is in its lowest position (when nozzle touches the plate), so this tab has very low rim protruding over the heat bed. Because of that build plate placement is still a bit finicky, but overall much easier than without it. Main reason why I made this is because I wanted to attach the cable chain and the bazzzzzzz model was unsatisfying for me. To print this you need to enable supports. But printing with PETG I had hard time removing the supports from the small slots on the bottom where protrusions of the attachment plate should enter. So maybe use support painting and disable supports there. The slots are pretty small and should bridge fine on any printer. Also the tab will heat up with the bed, so probably avoid PLA for the tab itself. For the chain and other parts PLA is okay. Use the chain itself and the frame attachment clip from the bazzzzzzz model. For Max you need 21 chain links and clips. Clips may be finicky to print, I had problems with them detaching from build plate mid print when printing with PETG.
