I’ve dropped Mark a note to look into this and add any “original design from” that may be needed in the description.


Hello guys,

The key was based on EA7HVO design for sure, but completely redesigned to my own using FUSION 360, I also have a single lever version exactly built in FUSION 360. I have designed other 2 keys based on this design but they are completely different…

@OE5JFE you can read the terms of the key licensed under the Creative Commons - Attribution license:

You are free to:

  2. Adapt — remix, transform, and build upon the material for any purpose, even commercially.
  3. The licensor cannot revoke these freedoms as long as you follow the license terms.

No arm has been done. I have been inspired by the very FB job done by EA7HVO but this is a more solid version.

If you have questions/remarks you can surely email me, no problem

But in order for EVERYONE to be happy, I asked Pete to add “inspired by the work of EA7HVO”.

And if you read the licence it says:

Attribution — You must give appropriate credit , provide a link to the license, and indicate if changes were made . You may do so in any reasonable manner, but not in any way that suggests the licensor endorses you or your use.”

IANAL but it looks like you need to say you took the EA7HVO design and enhanced it.


Yep, that’s what we will add.

Thanks for the clarification Filipe.

It was not ment to say that you did not make changes or improvements. But the origin is clearly visible and therefore the licences needs to be respected from my point of view.

I know that because I also did a remix of the original design in Fusion 360 too:
CW Paddle modified base (remix from EA7HVO) by OE5JFE - Thingiverse
It removes some visual issues and uses brass threaded inlets to hide the cables inside the 3dprint. And the base is modified to better fill for example with epoxy resis and coins (or lead speres or ball bearing) to increase the weight.
By using the remix-feature of thingiverse also the licences gets sets and the attribution to the original work is documented.

But everything is said now. I wish everyone a lot of fun with the 3D printed paddles. I think it shows nicely what can be done with 3D printing. And as it is for a good cause all good!

Your key looks a little less ugly than the UK version. Well done.
