this file has caps that print supports are built into the print just remove after printed supports may be a little tuff to remove depending on your printer but they do remove.Have added 2 files one is the caps themself other file is just the spinner in case you want to print the caps different color.I did a version 2 removing the footballs between the bearing and the viking head found that it is a little weak at the bearing end.Version 2 is allot stronger and also smaller which can be good for smaller hands.I also made a 70MM version of V2 and caps to fit it.
