Perfect for AMS HT and AMS 2 Pro drying cycles! These are hands down the best filament clips I've found! I printed 12 of them at once on my Bambu Lab H2D using BambuLab ABS (dried for 8 hours at 80°C in the AMS HT), and they work fantastically. What I love: - Super easy to use - no fiddly mechanisms - Excellent grip on all filament materials I've tested - Low profile design is perfect for use in the AMS HT and AMS 2 Pro during drying cycles while the spools rotate One small note: I had trouble threading the filament through the joint initially. The hole seemed slightly too tight, and I had to carefully widen it with a thin screwdriver to get the filament through smoothly. Once modified, they work perfectly. I chose ABS specifically because these clips are so useful during the drying process, and the AMS HT can get up to 85°C Would definitely print more and recommend to anyone looking for reliable filament management!
