Summary

The smallest dolly possible for the GT. I usually carry it in my backpack bottle pocket or in my sling bag.

This dolly clips into the gap in the rear bumper at the tail light, see pictures.

Features:

This is the smallest dolly design possible and lightweight so you can always carry it with you.
Works with stock rear bumper and any rear foot pad. If you have the TFL kush wide foot pad, you can even let the GT rest upright!
It does not fall off when lifted. It is designed to be pulled forward and not backward. Be mindful when pulling it over dips or gaps.

Other parts needed:

2 M5 40mm bolts.
2 M5 nuts. Prefer nylon lock nuts.
2 standard 3D printer V-slot wheels. They might not last long on concrete or asphalt but works well on smooth indoor surfaces. Replace the wheels as needed. You can get a dozen of these wheels for $10 on Amazon.

The Fusion360 design file is included. You can change the parameters (Edit > Parameters) to change the total width, wheel width, screw size. The bumper slot max width is ~148mm. I'm using the 100mm width version.

To put it on, push the front pad down with your foot so the rear lifts up. Slide the dolly in place in the middle of the rear bumper slot. Then pull it up on the front bumper with your thumb and pinky extended for lateral stability.
