[DIY] Phone Holder for Photogrammetry (3D scan) - 3D Print

I designed this phone holder to help improve photogrammetric 3D scan results. Can move the phone 360° around, at 3 different heights / angles, resulting in a clearer and more precise 3D model reconstruction.

 

It can be used for any medium-sized object. Each extension arm screws into the extension below, so a user can just print as many exensions as needed, from one station location to 2, 3, 4...

 

The phone is held with a standard articulated phone adapter mount that has a camera cold shoe base. It simply slides into the ring that comes with each extension, making it easy to move the phone from one height to another and change its angle.

 

Worked perfectly for scanning my feet, to help break in climbing & hiking shoes. Here is an early setup example and a 3D scan result (process will be covered in a coming post):

 

The Fusion360 CAD model (messy), STEP and 3MF files are on Github and MakerWorld

 

Feel free to copy, remix, whatever (non-commercially) 
 
Happy scans to all !

• Extensions & rings: print as many as needed 

 

Phone Adapter Mount

 

I used this one from Ulanzi

 

But any adapter will do as long as:

1. it is articulated in Z axis (see pic above) so that the phone can be pointed down at a steeper and steeper angle the higher it is positioned
2. it has a camera cold shoe base (screw hole not needed):
