A miter saw stop block that works with T-track systems. You need to bring your own M8 bolt > 70 mm that fits in the track.
This block can be installed in two ways:
Print the block alone – as shown in one of the photos with the black knob. This installation method is on-par with a lot of the storebought options where you have to insert the block from an end of the track.
Print w/ the end cap for M8 bolts with smaller heads. This option allows you to drop the block vertically into the track. See the video below.
