This is a custom stop block I designed for my fenceless miter saw system. Video of how the system works here: https://youtu.be/Cj-sCdSqw04
This part was printed upside down (with rails facing straight up). The only supports required are in the horizontal holes which were designed to accept 8-32 heat set inserts for mounting an optional plate. My plan is to make a thin aluminum plate with countersunk holes to mount on that end to create a very durable reference surface.
