The Titan Extruder is an excellent extruder with one small flaw, the lever that creates pressure on the filament also discharges this pressure onto the motor bearing used as the fulcrum itself. Pulling the appropriate spring increases both pressure on the filament and that on the motor bearing, thereby increasing friction and motor effort. This mod completely resolves this issue while keeping the lever aligned. It's possible to replace it with the standard lever without any other modifications... The MR85ZZ micro bearings measure 5x8x2.5 https://aliexpress.com/item/10-20-pcs-MR85ZZ-Ball-Bearings-In-Miniature-High-Carbon-Chrome-Aciered-Stainless-Steel/32949597823.html?albbt=Google_7_shopping&isdl=y&slnk=&albslr=234404027&src=google&acnt=494-037-6276&aff_platform=google&crea=it32949597823&netw=g&plac=&albcp=1705851092&mtctp=&aff_short_key=UneMJZVf&gclid=CjwKCAjwhbHlBRAMEiwAoDA3499DV8PVKYFcascW995oNuiX7WshdiMXPiCDeVSY0Mk8TH_KF9HKrBoCccMQAvD_BwE&albag=72263549488&albch=shopping&albagn=888888&trgt=296904914040&device=c&gclsrc=aw.ds The lever was inspired by this one but with radical modifications https://www.thingiverse.com/thing:2426505
