Aluminum Extruder Idler Arm Metal Lever Compatible with Sidewinder X1 All Metal Titan Aero Prusa i3 MK2, 4max pro Sovol SV01 3D Printer (Black)

tricky/fiddly to fit on my sidewinder, but holds better and doesn't move during prints. Great upgrade.

Changing to one star. As stated in another review, the poor alignment causes under extruding, with prints ending up with the finish of shredded wheat. Original review below..As others have said (but I didn't see before buying) the paint makes the fit too tight, binds to the shaft and causes the motor to scream.After filing the hole out and swapping the guide bearing out for the original concave one, this seems OK and hopefully won't snap like the original.

as someone else points out, the hole at the bottom end where the extruder motor axle passes through it is too tight, it sticks on the shaft. and even if you drill it out, it doesn't quite align properly with the hole the filament should go into - creating extra friction and resulting in it underextruding

The hole where the extruder stepper motor shaft is meant to pass through is too small and binds to the shaft, making the bearing useless and causing the motor to skip all steps. This was tried on a Sidewinder X1.

it does what is stated in listing

Funziona perfettamente per la Mia artillery genius ed è di ottima qualità, Consigliato per chi come a me sì è rotto quello originale!

Parfait pour remplacer la pièce cassée de mon extrudeur de l’ I3 mega S (titan aero en plastique).Fonctionne très bien. Tout les roulements à billes sont fournis ainsi que le ressort (bien qu’un peu plus petit que celui d’origine, ce qui ne gène en rien). Le remplacement est facile. Aucun défaut constatée sur la pièce, qui a l’air très solide, et la réception s’est faite un jour en avance.

I really just needed the spring after I lost mine while reassembling my extruder. I put this on and it performs as expected.

Montage parfait pour ma sidewinder X1Je recommande
