Well, thank you… but I’m sorry about you needing to dismantle the carriage to install it. I put so many mounting holes on that backplate to accommodate different machines… I guess I missed yours. 
Actually, I later settled on a completely different Z-lift design that is a lot simpler… and uses that Neje mounting clamp for a sturdier hold. I designed it specifically for the $79 Amazon machine so the hole pattern would need to be altered for your machine… should you want to adapt it to your machine.
I like that purple filament BTW…
