Recently friend of the blog, Greg Cassidy, did a YouTube Short on Kelly’s magnificent 3D printed HO scale wheel stops based on the prototype. Have a watch:
A few years ago I was lamenting to Kelly how there were no good HO scale wheel stops on the market. Nearly all of them look chunky and oversized. (because they are.) We visited a stretch of abandoned Georgetown Branch right of way in Bethesda where a siding still exists that includes original wheel stops. Kelly was inspired to draw up a model in Fusion360 and printed a few test items before developing a final design. Here are a couple in place on his layout:
They are simply the finest wheel stops on the market, full stop. (pun intended.) They are 3D printed in resin, are quite durable, easy to install and if they break, you can simply glue another one on. Kelly sells them over on his site, FineScale360. Get a few for your own layout!
