In order to make the most commonly available version fit, you can strip of the plastics from the power pins and carefully bend both GND and Vdd pins in a Z-shape so they will fit in the adjacent pin hole.

This way the display is still positioned correctly to fit in the many available 3D printable enclosure designs out there.

This catch-22 situation can be resolved by adding a simple diode from GPIO-0 to the "3.3V" pad. (the 'line' on the diode towards the "3.3V" pad)

In this test setup, a basic 1N4001 is used, which has a voltage drop of about 0.5V.
Another option is to use a germanium diode like the 1N4148, which does have a voltage drop of 0.3V.
