Noctigon KR4/KR1 18350 Lanyard Ring (3D printed)

This nice Noctigon KR4/KR1 with a 18350 tube that could be carried very nicely on a keychain or some other kind of ring/carabiner etc. does not support the nice stainless steel lanyard ring! D’oh! My first workarounds using various techniques of paracord knotting were too bulky, ugly or both.

3D printer to the rescue! Here’s a little model I designed very quickly in OpenSCAD. Just screw off the tailcap, slide it over the tube (yeah, now it has three tubes!) and screw the tailcap back on. I designed it so that it can be printed without supports and with a 0.4 mm nozzle the thinnest part should be two perimeters thick.

Here’s the STL file and here the OpenSCAD file.

That is a clever approach and a very nice implementation of it. Thank you!

I don’t have a 3D printer yet, but I just got put onto Treatstock recently, so I finally have a reasonable way to get 3D printed parts.

I’m sure there are at least some people in your area who have a 3D printer. Maybe try to find some kind of maker/hacker space or other local technical group.

I have a printer, but I’m a few hours north.

There is a maker space in Madison called Sector 67, they seem like a bunch of nice people from my limited interactions with them.
They gave a mini CNC mill to the maker space in Appleton a few years ago.

They might have someone who would be willing to do small prints for cheap.

lol
one of my favorite things to do is come up with big ideas if other people are going to do the work!
