I did it and I'm very satisfied with the result. Though I went full diy and ordered parts individually. I did all of the printed parts from recycled PET from bottles which I recycled myself. The rest I ordered from aliexpress. I have a previous version, didn't get around to update. I made an adaptor for herome gen 6 hotend holder and made it with mostly stock e3d v6 hotend. I just added a cht nozzle. Don't need anything else. But the best mod IMO is the dual z axis which I recommend even without mercury conversion.
Edit: I did it on ender 5, have no clue what's the difference on other printers.
Oh, yes, it caused weird resonant vibrations at certain speeds. A terrible design and way too flexible bed. Some people print some struts, but I didn't find them to be much of a solution. I ended up mirroring the far side and copying it to front. Now it's very rigid and the quality has vastly improved especially at speed printing.
