So I finally have the F1 completed and noticed that the rear axle seems to snap fairly easily. What materials are people using for the axles? I tested with eSun PETG as well as Taulman In-PLA.

We’ve tested some in PC and PC-ABS which holds up good. Also @Anton_Mansson ​ runs a XT-CF 20 rear axle.

Thanks! I’m giving Alloy 910 a shot since I have that on hand
