Ordered one, hope to print TPU without a direct drive swap. We'll see.
I realize you can print an equivalent but this metal one was cheap enough.

The metal spring arm is a must have -- the original plastic part will eventually break.
This
might
help
some
for TPU, but a "direct drive" is really your best bet. There are lots of 3D printed brackets that let you move the extruder ontop of the hotend reducing tube length to about 2 inches and no bends to push through! -- works well and costs nothing to try!
And the final piece for me was a 3D printed bit on the extruder itself -- give the filament nowhere to go but through the gear/pulley and into the tube/hotend. Very pointy, hole just barely big enough. A while back I tried to find one of these in metal, but no dice, so I've been using a petg one for years. The only downside is when unloading hot filament, take care to pull long and straight, to minimize melty filament sticking to it. I've had to redrill the tiny hole a couple times in as many years to unclog it, so it's rarely a problem.
