I’ve started printing TPU, and I have to make the “grip” on my BMG clone extruder extremely loose to get it to extrude properly. Otherwise, the TPU will jam.

The downside is that hanging my spools off of a static hook does not cut it anymore, as the extruder does not have any “grip” to pull the filament.

So I’ve started looking into spool holders that use bearings to reduce friction on feeding filament. Is TUSH still the gold standard? If not, what is?
