Hey, thanks for your input and I'm glad you're enjoying the stock!
The naked adapters have some tiny dimension changes but I'd say go ahead and cut a profile on the ones you have printed already, it'll save you a new print. Meanwhile I'm working on getting all of this fixed (as soon as a bunch of magnets I ordered arrive) by building a magnetic version for the grips and thus eliminating the controller issue from the equation. I think there's a 'Watch' option to follow project updates, so you can look out for that in the near future :)
Regarding the print button getting stuck in the adapter, could you please reply to this comment with a picture of it? I'm having trouble visualizing what's going on - I'll be sure to fix it.
