This is a remix of the JLTX Z toppers pre Taurus. I've only included the right hand side but if you use the mirror option in your favorite slicer it'll work out for a left hand variant.
You'll need an M10 pass through pneumatic coupler which can be found on Amazon.
You don't need any supports and there should be a super tiny stem that supports the one hole that looks like it needs a support. Just pop it off after printing.
