Special Socket

Todays little project, fix my RC Yacht Transmitter. The nut holding the antenna connection has come loose.

Tried to get a socket in there - Wont fit
Tried to get pointy nose pliers in there – Wont Fit
Tweezers fit but - not strong enough

How do I overcome this problem, lucky I got a 3d Printer and Fusion 360.

Open Fusion 360
Draw a 11mm Circle
Draw a polygon 8mm across the flats
Extrude

Draw a circle on top of the extrusion
Extrude
Draw wings for the wing nut
Extrude down add a chamfer

Save as an STL file

Open the Stl file with Prusa Slicer
Export to G-code and print. Have a cup of coffee with the wife while it prints(34 minutes)

5 minutes drawing and 35min printing
Tighten the nut with the new tool – Job finished

Scale the item in your slicer to make any size required
