Surface grinder stops.

These look great! Definitely going to hold up for a long time. We have been making these ourselves with a much less capable 3D printer for over a year and have had to replace them on more than one occasion. These should last several years if not substantially longer and will certainly perform better than the flimsy/fragile ones we made ourselves. The price was also great, and the efficiency of the parts order and delivery process was much faster than other online options we have tried in the past. We will definitely continue to use PCB way going forward.
