Lever for Soap Dispenser

I created a lever to replace the arm that broke off on my soap dispenser.

The holes on the part are 3.6mm in diameter in which i just screwed in a M4 Bolt.

I printed the part in PLA with a 0.15mm layerhight and 20% infill. Here i changed the cura settings for the walls to 2mm for regidity for the thread.
