Befenybay 3D Printer Accessories Editorial Review
The Befenybay 2PCS 6.35mm to 10mm Flexible Shaft Coupling is an affordable and good-quality coupler made of aluminum alloy for 3D printers and CNC machines. Customers have found it to be a perfect fit on different printers with both 5mm and 8mm sides tightening down well. It adds just enough flex to avoid undue wear on the brass leadscrew nut and reduces wear and tear. However, if used on a vertical axis, a spacer needs to be created to fit between the shaft ends to avoid compressing the coupler. One customer noted that only one of the couplers was properly sized, requiring them to bore out one of the holes.
