Mitchell 300Pro Crank Case Cap

This thing is the handle cap or screw that covers the unused
one of the handle holes in the casing of the spinning reel Mitchell 300Pro.

I lost this cap on my last fishing trip.

To produce the threaded part of the cap, I used the OpenSCAD file
'Nut Job' nut, bolt, washer and threaded rod factory by Mike Thompson 1/12/2013, Thingiverse: mike_linus.

The outer diameter = 10.8 and the thread step = 1.2.

This thing was made with Tinkercad. Edit it online https://www.tinkercad.com/things/l0Y7x3B4oy0
