This is a smaller nozzle for the Metabo BP 18 LTX BL and Hikoki RA18DA (both use the same connectors and are technically identical) cordless blow gun which may become handy in some cases.
I printed it in PLA, but as the compressed air gets a litte warm for long time uses PETG or ABS may be the better choice.
Use supports when printing!
