I designed this as the other models always had one area that needed improvement.

Features over other nozzle brushes:

• Ergonomic design
  • Cutouts for fingers and thumb
  • Nice comfortable rounded edges
• Hole to hang on peg board
• Printability
  • No need to worry on printability of rounded corners. I designed this part to start with a 45° chamfer that leads into a fillet, meaning no ugly wavy overhang fillets on the first few layers

I would suggest printing the PETG model for extra temp resistance and the added flexibility PETG has making it less likely to snap.

I would suggest printing the profile with a Brim as you may get slight lifting at the very ends without one.  Nothing that would cause any issue though, just aesthetics.
