One of the things I continue to worry about with my A1 mini, is putting pressure down on the Z-Axis when removing the PTFE connections from the AMS Lite Filament Hub. The rings are very small and difficult to get to with my stubby meat hands. I looked at the other removal tools out there, but none of them met my needs:

• PTFE holes had to be big enough to not scratch the PTFE, but small enough to not move around too much (so you could pull it back up the PTFE if you don't want the extra 5.5mm of height on the Filament Hub all the time.
• Needs to provide enough leverage to push down the PTFE connectors (this is why they are extruded a bit)
• Needs to not add too much extra height (only 5.5mm added to height).
• Need to be able to pinch to remove without putting pressure on Z-Axis.

The plate has both the round and rectangle versions, so you can try either. The clip that goes around the AMS hub is small enough to leave on as it still allows the filament hub to “spring”.

EDIT: I have updated the models and 3mf so that they stay flat on the printer bed without the need for a brim.
