Hi,
Yes those parts will probably work, but they are a ripoff of Helder's work (and the 3d-printed parts I designed that they are selling are released under creative commons non-commercial license on thingiverse). So I've removed the link to the listing.
That said, we are finishing up version 3, which will have several huge upgrades over v2, so it would be worth waiting for that.

Should be ready in the next month or two.
