Spoolock - Retention for Bambu reusable spools

This is a simple spool retention device for keeping Bambu Labs spools locked closed. I had a couple of reusable spools that were starting to get a bit loose when opening and closing them and I didn't want to risk them coming apart in my AMS. Currently this is just for locking the spools so they can't come apart accidently, however I am working on a simple desiccant holder that can fit inside. This prints fairly quickly and does not require any special settings or supports.
