I decided to make a lower bearing race for my headset first. The frame I am building, a 17" Fuji Suncrest, came with most of a Ritchey headset. The lower race was not part of the package, so I decided draw one to fit the specs. This is a good test of part fitment because it mates with metal parts in every direction, it fits around the steering tube, on top of the fork crown and has a sealed bearing pushing down around the top.

|It fits well around the bottom|
|And fits the bearing perfectly.|
This is only a small part, and as of now it is completely untested, but it does show promise. Dimensionally, it is very good, the surface finish is a little rough compared to other bike parts. I think that there are many bicycle bits that could be printed, I'm going to continue this quest and see what is possible. There will probably be some great failures when testing begins, I'll be sure to document any magnificent crashes. It will be an adventure of grand proportions! Maybe...
