I wanted at least 4 sets of strap clamps as good ones can be £20 each. I couldn't find any printable ones that I liked the design of so this is what I came up with.

My take on the AMS spool weight. I couldn't find an existing design that I was happy with that was compatible with both the official Bambu Lab spools and the printable version, while also being easy to remove without unscrewing and spilling desiccant, plus I fancied designing something that could snap into place in a satisfying way.
