Brake lever extension

I've added bar ends to my bike, but I couldn't reach my brakes then. SInce I have hydraulic brakes, i didn't want to replace the handle. only option is to extend the brake lever. This is a simple prototype which does not make my steer too long, or the brake lever too bulky. I tried to make it as slim as possible without losing structural integrity. A M4 screw is used to keep the extension tight on the handle. printed with PETG and 3 walls and it's strong enough to withstand braking pressure.
