Summary

These are two piece, easily serviceable, filters for you electrical box or cnc controller. A house filter from your home improvement or hardware store will need to be cut down and put into the base and then the cap just clips over top. There are two sizes. The larger measures 80mm x 200mm with six mount holes and the smaller one is 80mm x 160mm with 4 mounting holes. Either m4x10 or #8x3/8" screws should work for attaching to your project. The picture shown is from my previous design, but gives you and idea of how it should look.
