I made a little brush to clean all the nooks and crannies of your keyboard and whatever other little places you have that are getting a bit dusty!
Print at 0.12mm layer height, if using Bambu Studio set your wall generatoer to Arachne.
Once complete use a sharp knife or scraper to trim the string holder off and start using your brush!
