Filament Clip, AMS Compatible, Ultra-Thin

I bought many different color bambu filaments, it's quite interesting to try different colors with the help of AMS. The filament clip is an important accessory. I have tried several popular filament clips, but it's inconvenient to remove clip every time I change the filaments in AMS, and the clips make it impossible to align the spools when they pile up. So I want an ultra thin filament clip that can perfectly hide inside the spool and AMS compatible. The Bambu resuable spool has 4 pairs of holes that are ideal anchor point for filament clips, but the clip should be as slim as possible, otherwise it will obstruct spool rotation in AMS. After trying different parameters, finally the 3.2mm clip can fit the AMS groove. I would suggest installing 4 clips in one spool, so that you can always find a nearest clip and the weight is evenly distributed. Hard to unplug the filament clips? No problem, here is the unplug tool. If you like this design, feel free to download, print and try it, or sim
