Dremel (TM) Stand Nut

My students, on a day I was away, thoughtfully dismantled the Dremel stand to try and remove the rotary tool... We had to replace several parts that went missing, but the most difficult was finding the correct nut for the pole anchor.

So I challenged myself to make one. And after four or five iterations, I found a design that worked nicely.

This thing was made with Tinkercad. Edit it online https://www.tinkercad.com/things/1eNySzMcSmS
