Funny, last week this conversation came up on a FB group I follow. I used the technique Glen outlined on my 3d Print ROTK. The mesh fabric found at most hardware stores is a very flexible plastic that can easily be held in place with a few drops of hot glue. This is a very simple install.
Please excuse the sloppy interior and the chips from where I dropped my bucket on the driveway.
The only issues I have with it is that all the window screen mesh I've found stateside appears to be square shaped rather than rectangular if that makes sense. Also, the fabric is not "woven" and seems thinner that what's available overseas. I told people that this mesh will hold you over, it's cheap and easily obtainable, but keep looking for something a little more accurate. One of the German members posted a pic of textilene mesh which is commonly used for outdoor furniture and seems to be a great option. Also, someone correct me if I'm wrong, but I just looked at all the TK CRLs and they all simply say "mesh," but don't really specify the type or details.
This looks like some amazing work, but someone definitely needs to explain what's going on inside this bucket. Is this a black series conversion? It appears to have a regulated air system and pretty complex electronics, but I can't tell.
