Brush
thingiverse
Brush for cleaning things. This was printed in PLA at 0.2mm layer height w/ a 0.4mm diameter nozzle on an MK3S. DON'T PRINT THIS IN WHITE! I'm sorry but it's not the best model, I cannot design a better one until I upgrade my computer. It still works however, it just takes unnecessarily long to print and has way more vertices than necessary. I bet you could do a better job designing one and encourage you to. If you wish to make your own, just use 0.5mm cylinders like I did, or better yet rectangular prisms the size/shape of your layer height/nozzle diameter, I haven't tried that but it should work just as well as cylinders but w/ less vertices. (credit to 3DPProfessor for the rect idea)
