I made one of these for my DeWalt DCW200 square sander and my ShopVac brand wet/dry vac. Everything fits like a glove. My sander is different than yours and a couple others on here, but this works beautifully. Absolutely zero dust flying, from what I can tell. Huge improvement over the stock dust bag. The print profile is great. Although I added an inner and outer brim on mine, just as a precaution. Thanks for sharing your design!

This is really great and, FYI, it works great on Tundra deck rails, too. Picture proof added. :). Easy print, and I printed in PETG just to ensure strength and ability to handle the environment in the back of my truck.
