Hi PDBeal,
Sorry for my late answer
As long as the Sentinel is installed before an extruder, bowden or direct-drive, it will work. The PTFE tube doesn't actually need to go up to the extruder. The two fittings hold PTFE inside the sentinel, which can be extended based on the user setup.
The Sentinel has two mounting holes, you can install it on any flat surface very easily!
Hope it helped!
