A1 Filament Buffer Squeak Stopper

Have you added an AMS with filament buffer to your A series printer and printed the Bambulab mount for it? When the buffer starts squeaking, remember this doodad. It's a simple slide on guide for the PTFE that helps keep the buffer from touching the sides (and squeaking) as it goes up and down. This is designed to be strong in the proper directions, adds less than 10 g of weight to the z-axis load, and prints with no supports or other special considerations. I used PLA because it is stiffer than PETG but most any non-exotic filament should work fine. To install, disconnect the PTFE from the outlet side of the filament buffer. Stretch the ‘legs’ of the squeak stopper and slide it between the buffer and the mount then push it all the way down. When it's seated, gently pinch the bottom of the squeak stopper to make sure the grippers are secure around the bottom of the mount. Feed the PTFE through the hole in the squeak stopper and reinsert into the outlet side of the filament buff
