Airborne Dan spool lock

I tried a couple different spool locks, but wasn't happy with the way they worked. Mostly, I wanted a more secure fit but also wanted it to be not too hard to remove. This spool lock fits the wider spaces in Bambu Labs reusable spools. It's a firm fit and once inserted won't come out by itself. The tab makes it easy to grasp and get out once it's inserted, but it will stay fitted until then. If you're using this in spools that will be dried, you'll need to print in something that can stand the temp your dryer reaches. Also, this won't work on a standard spool holder, it's intended for the AMS where the spool rides on the edges.
