Connecting Multiple Devices to 3.3v pin w/o Using a Breadboard

Question: What is the best way to supply 3.3v to 2 devices I have and potentially more without using a breadboard?

I have an RedBoard, an AD8232 heart rate monitor, and a Nokia 5110 graphic LCD 84x84. Both the AD8232 and Nokia 5110 need 3.3v for power. Normally I would use a breadboard and everything would be fine but for this project the goal is for the end product to be stand alone. No computer, no breadboard. Essentially I am making a free standing electrocardiogram (ECG) that displays beats per minute (BPM) as a number.

Theoretically I could make a small circuit that connects to the 5v pin and convert the voltage to 3.3v, but I expect to be adding more to this project, such as an alarm buzzer, so I'd like to avoid taking up more power supply pins.

My professor suggested connecting 3 male pin headers together, and putting one in the 3.3v pin then connecting the devices to the other 2 pins. Would this cause to much current/voltage drop? How would I go about doing this? Using only solder seems like it would be a poor decision.

Solder is what the electronics world is made of.

Take a look at each of your modules. How are the components connected to the board?

I meant connecting the 3 male pins together with a line of solder. Though I suppose that'd be better than stringing wires together.

Strip the ends of the wires and twist them together. Ads a little insulating tape. Even regular stickytape works if you don't have electrical tape.
