That's pretty rad!
I've had a MH871 for a few years now, and I just realized the blade holder clamp tilts when you tighten it! UGH.
No wonder my tiny letters are always popping out on me.
Was thinking of the MK2 carriage, a new 3D printed clamp, or somehow fitting another clamp to it - but now I see your post and I' wanna see that!
Cheers,
