Poor Mars knob

I needed a door knob, so I made a quick one. It's called that way, because there are couple of irregularities that I should have eliminated, but nothing you can see when model is printed - as I said, it's made for its purpose and nothing more.

**I used parts from NUT JOB by mike_linus, particulary:**

>Nut joiner for threaded hole in the knob;
>Bolt 25x8 printed seperately;
>Washer 1x8.5 printed seperately.
