Description

My Ender 3 Pro's Y-axis got upgraded to 9mm belts and I needed a new motor bracket. This is the result of a few weeks. Double shear support and live-shaft pulleys. Requires 9mm 20 tooth GT2 pulley, 10mm 40 tooth GT2 pulley AF-type (I printed mine), 5mm diameter shaft, an assortment of M3 screws, and 4 M5 screws. Also some F625 and 625 bearings.
