/diy/ - Do It Yourself

This is a power adapter for my RV. The depth of the plug d is greater than the socket, such that the threaded collar just barely doesn't reach, leaving the plug floppy and easily knocked loose.

The first idea is to make an adapter collar and use the threaded black piece with the profile in red/cyan (lower) in a circular sweep. The concern is the layer lines don't provide much strength in this direction and some difficulty getting it to both slide over the existing geometry but still provide support. The yellow is ever so slightly flexible s.t. you can barely remove the black.

The second option would be reprinting the entire black collar, but extending it. The force/layer problem is the same however thicker profile is possible as it only needs to interference clear the one yellow piece. The concern is both layer strength and more being able to reproduce the fine threads. Most of the 3d printed screw threads I've had success with are oversized.

Thoughts? I'm not sure which to pursue or if there are some alternatives I haven't considered (e.g. chopping the yellow end off)
