Smartphone/Camera Dolly Car

Build your smartphone or camera dolly car in the simplest way. 

You only need a standard hot shoe mount adapter, like the one we all have in our photography backpacks. 

 

This adapter works as both the main axis and a 1/4" mount. Not only does it make it stronger, but it also allows you to mount any professional cell phone mount or tripod ball head.

 

 

 

If you don't have a cold shoe adapter, this option from Amazon should work:

Although this ball head and cold shoe package is a better deal:

This dolly car can rotate up to 40 degrees to make circular shots.

 

I recommend using 20% or more sparse infill to make it heavier and stable.
The wheels are assembled individually with an axle and a cap for rolling. Although the pieces fit together tightly, for best performance, I recommend using a little glue on the joints of the body.

 

 

 

 

UPDATE

Add a file with a buildable track for straight shots. Just print the segments you need for the desired length and assemble them. Hope you like it!

 

 

 

UPDATE 2

Added a print profile with a TPU cover for the wheels if you find the stock ones a little slippery. They also absorb a little vibration making the movement more soft.

The TPU settings for a great print are provided by@allfor3D and his great The Perfect TPU profile
