This is a blower adapter I made for a Milwaukee M18 blower. It concentrates the air. I did it to remove snow on a car. I tested it once and it worked. It is really easy to print. I put the rectangle on the bed and add a raft of 4 mm to be sure that it will stick all the way to the bed.
I designed it with Openscad. The file is there, so if you want to change something, it is up to you. The comments in the script are in french, but it is easy to translate with Google translate.
I hope it will be useful for others, enjoy!
