Printrbot Simple Metal Spool Guide for ALU handle

thingiverse

This spool bump serves as a protective barrier for the Printrbot Aluminum spool rack, ensuring that a spool won't get caught on the screws securing the rack to the handle, which could cause printing issues. To set it up correctly, first print the Spool Guide. Once printed, slide the guide onto the rack, making sure the hook faces downward. Next, align the holes with the screw heads and press firmly down on the hook until it clicks securely into place around the rack.
