I'm back much faster than expected with another mass produced twisty puzzle! It's pretty much the exact same story as before but if you're interested, you can buy the puzzle here. It has very good build quality and is worth the price if you're a collector.
Here it is compared to my original shallow mixup cube.
My original 3D printed version used curved cuts which complicated discussions with this company but eventually we reached an agreement. Also they are working on a Son-Mum Plus cube which adds the additional edge pieces in my original design.
And here are more pics!!!
