About this 3D model

This is the second item i have put up so still a novice On the first one i used elastic bands to give the down pressure on to the tap It works well once it get started I used a 6mm tap and a old cordless type drill to turn it It was printed in PLA so i have added a oiling vent on so you can keep the tap shank lubricated V3 has 8mm bearing and center shaft clamp plus handle
