Kobra S1 ACE Roller Extension

Spool Roller with increased diameter for smaller Spools than Anycubic to support smooth run of spool If the spool is too small for the ACE(same with Bambu AMS and probably others as well), it sits on the bottom and creates unnecessary friction, hindering material transport and thus leading to reduced extrusion. This causes printing errors and likely also overloads the drive mechanism. printed in PETG Standard preset 0,2mm Ø16 & Ø20 available Just swap the original pin and click back in ACE.
