Printed in PLA. Fits well. If you use other material you may have to compensate for shrinkage. Really, there should be another way to put print settings in without having to upload a print of my own design... Anyway, I printed this as fast as my little printer would go. Turned out reasonably well, though took some cleanup. Rough printing leaves little bumps on the connections that need to get scraped off. Printed both in one go, 90 min.
