DIY Mill Vice Speed Handle in Cast Aluminium

My import Kurt style milling vice came with a massively oversized handle which is awkward and difficult to spin quickly when you need to open or close the vice a lot. What I need is a smaller speed handle but because I hate spending money I decided to make my own. This one is cast in aluminium from a 3D printed patterns and it has two modified deep sockets set in the casting with loctite and M6 socket head cap screws. If you would like the STL for the pattern I used you can get here (free). https://www.dropbox.com/s/7lqogwu08b3...
