Weight machine cable management brackets

I friend brought me a handful of broken pieces that were part of his weight machine. He described them as cable brackets that kept the cable on the pulleys of the machine while the weights moved. I designed and printed them without seeing the system, he told me the next day they were a perfect fit and he was able to safely use his weight machine again. I do not have the name or model of the machine these were designed for, I'll just put them here in case someone is looking.
