Roller Nut and Race for Crossbow
thingiverse
This is a roller nut and race for a medieval style crossbow. I haven't printed it yet. The plan is to print it and use it for lost PLA casting. The insert for the sear is a 3/8" square piece of case hardened 1/8" steel. Make it shiny. All pinholes are 1/8". For the roller nut either ream the hole out or use a slightly undersized pin to facilitate rotation.
