I ordered a bunch of parts from PCBway the other day. I reordered enough of the printed parts for the fingers that I could have an as printed and refined group of components so I could show the amount of work that is going to be required to assemble the fingers into an operable assembly. I also ordered machined first articles of the winder assembly. the parts showed up near perfect! The only work I had to put in was passing a 6mm reamer through the bearing holes, and a couple of swipes with a file on one of the bearing stobs of the fork. the through holes were sized perfectly for the 4-40 threading. and everything stacked up correctly.
