Credit to @Jonathanlin for including the f3d file that made this an easy first remix!
I did slightly reduce the diameter on the side that connects to the Cloudline S6, the fit is very tight so make sure your printer is well calibrated.
I also included to f3d file if you need to modify any parameters further.
Prints as is without supports, 3 perimeters makes it solid.
PETG recommended, 203g.
MK3S+ 0.6 nozzle at 0.2 layer height with default speeds the print was 8h50m and turned out great.
The author remixed this model.
