A dust extraction nozzle for Makita multitool (DTM50Z). Has the same size outlet pipe as their 18V router, or the other dust extraction nozzle I've made.
Best to print in something like Nylon/CF I think.
Messy design I'm afraid, but I needed it in a hurry. Also, it's a fraction tall for Prusas (210.87), but you should be able to lose ~1mm from either the top or bottom without issue.
The author marked this model as their own original creation.
