Mini lathe chuck nut holder

I liked martin8's lathe chuck nut holder for mini lathes but I have a 5" chuck on mine and needed extra reach. Martin8 also posted one for a larger chuck using a m8 nut. I copied his design of that but reduced the end to use the M6 nut of the smaller unit. Posted here are the top and bottom case halves. Use the gears from https://www.thingiverse.com/thing:3245166 and print the middle gear from https://www.thingiverse.com/thing:3254426. That gear prints at a thickness of 5mm so I printed the mid gear at 60% z-height because I don't have the knowledge to change the STL files posted here. This gave me a finished height of 3mm which fits in the case.

Update: A guy on a FB group identified a problem which I corrected. I deleted the bottom file and uploaded the modified bottom. This should solve the clearance issues. Thanks, John!

Update: learned how to insert mesh and edit. I uploaded the mid gear at 3mm thickness.
