Griffin carriage bolt reinforcement/tensioner

Custom, beefed up tensioner for the Griffin delta printer carriage. Built to use two 30mm M5 bolts and five M5 nuts. It mounts to extra bolt space on the back side of the carriage. I recommend using at least 50mm bolts on the carriage to be able to use this part. Performs a similar role as thing:618024 but is much stronger. Also, the bar can be laid on its side if your printer can handle the overhang the empty box creates.
