Weller 25 watt soldering iron holder adapter

The Weller soldering iron comes with a reuleaux triangle shaped front that doesn't fit into my soldering iron holder. I made this thing to adapt it. Works really well with the 25 watt iron. I am not sure if other Weller irons that took this same shape will fit. The iron fits just snug enough so you can put it in and pull it out with one hand, but keeping it upright and centered in the spring.
