Visible Spool Lock for AMS Spools

I only use filament with my AMS V1, so I wanted a visible Spool Lock that I could better see from the side of the spool to give me peace of mind that they were locked. I developed this model after many iterations to neatly slot into the Bambu Lab Spools and prevent opening of the loaded spools. Should also work with the AMS2 Pro with Bambu filament spools. 

Instructions: 

• Print the spool lock. 
• Slot the spool lock in the the smaller notch on a locked Bambu spool.
• Ensure the lock is pressed in until the lock symbol slots past the inner edge of the spool. 
• Color in the lock symbol with pencil / marker if desired. :)

NOTE: because this lock protrudes within the inner diameter of the spool, it is not compatible with side-mounted spools or AMS-lite. Alternately, you can use Print Profile 2 for a low profile lock that should be compatible with side-mounted spools or AMS-lite.  

Suggest printing this in PETG or another heat-resistant filament, especially if using this lock in a filament dryer. PLA works as a lock but should not be used in a dryer.  

Please leave a thumbs-up if this model helped you out! :)
