I printed this for my Neptune 2S

this print needs supports
I used lines and it came out great
print on a raft for best results.

the roller requires 2 standard 608 bearings.
the two circles depending on how close your printers detail is, may or may not need superglue. I have printed 4 and only 1 needed superglue other then that it press fit just fine.

the slower the better for this print.

I made the pin so it would take a standard cotter pin 1.38 x 28. just a small pace of wire would hold it.
