BNC dust cap

This page was last updated : 10-May-23 10:11:50

After working on my Elecraft K2 I accidentally connected my antenna to the wrong port and it took me 15 minutes to find out what the problem was. 
So to prevent dust and stupidity I designed a simple twist and lock BNC dust cap. I have tested it on all my BNC chassis parts in the shack and it fits all of them.

Now the un-used ports are capped for dust and stupidity. 

 

 

Make your own, get the STL File

Let's try something different

For the  3D designs most of the time I use Tinkercad (as shown above) but I have used Freecad in the past for some simple 3D designs. 

So to compare I wanted to redraw the dust cap into FreeCad. And after a few hours, most of the time was searching and reading manuals, I managed to draw the dust cap into FreeCad. 

It's harder to work with then Tinkercad but it's a very powerfull application with lots of features. 

For those interested, I'm willing to share the FreeCad design file. Just send me a e-mail or use the contact form. 

 

Want to have, but don't have a 3D printer

When you don't have a 3D pinter and don't know anyone who has them, I be willing to print these parts on demand and sell them to you.
