MK7 Drive Gear Lathe Hobbing Tool

I create this tool to cut MK7/MK6 Driving gear on my small lathe. It takes two 7/16" ID Bearing(McMaster 2780T56) and 7/16" 304 Stainless Steel Rod(89535K173) for hobbing.

Instructions

Print one holder and two collars at 100% filled.

I use M3 Tap to hob about 0.1mm depth of cut.

On my small lathe, it takes about 15 minutes to reach this depth.
