Well it's not a Greenhill's Cube, but I have not seen it done before.

I have made a Pocket Missing Link and an Extended Missing Link before so I took it one more level this time.

Here is my Mini and Mega Missing Links.





On the Mega Link, instead of having all 4 middle sections fixed, I decided to do 2 and 2. Here is how the middle sections move.

I also made a staircase cube

FYI,

These link puzzles are not made from the Ideal Missing Link. They are made from some type of clone Link. They have springs and bearings in them so each section clicks into place. I do have 2 of these links with their original boxes if anyone wants to make a nice trade or offer.

I made a puzzle like your Super Link, but yours looks a lot better.

That's the one I made.

Humm, I wonder if Jaap should update his puzzle page for a solution to the mini Missing Link ?

I admire your courage to have mix-up the mini M-link

On the staircase cube, do the end pieces rotate together when they're all on the same face like on the 2x2x4?

The extra 4 pieces are just glued on. The problem is with using an original 2x2x2 pocket cube. The cubes are not solid and need to be filled in, sanded, etc so they can be attached. This puzzle does make some cool shapes when scrambled.
