About this model

This part supports the top of the ACME rod that drives the Z position. It utilizes the smooth round guide rod and the top cap screw. The stock screw is long enough to be used, so you dont need to use additional hardware. It requires a bearing and any skate shop will have one for cheap. They are the same ones that you find on your skateboard. I purchased a used pair for $1 each. Let me know in the comments if there is something else that needs addressed with this part. 02/15/17: Updated file to correct scaling and added the original Sketchup drawing. 03/05/17: This part is a bit deeper than the bearing because a lot of the time, the Z-screw is lower than the opening on top.
