An easy print all things considered. I think you could do without the rubber bands to act as "grip" to the camera mount...it makes adjustment overly fussy, if you ask me. Users of older thicker phone might want to make an adjustment to the Locking Lever. I found that the case on my phone (a typical thin 'wrap around' for a Galaxy S3) was a bit thick for that locking lever, another 2 mm of arm height would work better for my phone.
It a nice mount for taking close focus pictures of small objects. If your 3D printer can make or if you own small objects you need to photograph it works nicely, you can get a good focus on details because the phone and base are locked down.
