Hello,
just to check if I understand it correctly - when I "[p]lace [the bearing] in the declavity in the idler holder" and put the M4 insert into opposite side - these two parts (rod and thread) stay there only if I put filament in-between. Is this correct? Because everytime I remove the filament the larger gear falls off. Shouldn't I glue those two parts so that they stay in-place?
