I printed Gears1_V8E_PrintInPlace.stl in ABS and PLA.
Settings see in the makes.
Cooling is essential, as otherwise the vertical gears melt back to a round blob.
It's a challenging print, not all printer-filamenttype-temperature combinations will work.
The disassembled V7 works as backup, if Print-in-place doesn't work for you.
The design has warping potential, so heated beds help.
