I happen to be the person printing them. 0.8mm nozzle, and 0.3mm layer height for them.
Using 2.7.something for Cura, 2.4mm Walls when possible (3 perimeters if possible, probably complete overkill), using the recommended infill percentage on the parts page I found elsewhere on this site.
The biggest problem as I see it is that the larger the nozzle you use, the more ooze you get, so some of the parts will need some slightly more aggressive post processing. The printer I am using has a bowden feed, and I haven’t really dialed in the retraction for printing like this, so the supports on some of the prints are a hot mess. Nothing a quick pass with a drill bit or a needle file won’t fix though.
I have been having some issues with printing the Roller parts, but I don’t know if it’s filament related, slicer related, or the printer needing some non obvious maintenance. Looks like I am going to have to actually watch the part print to see what it going on.
