Fine-Adjusting iPhone Holder

Background

This is a summer project I did for my Dad who wanted a way to take pictures with his iPhone through binoculars.

Problem

Binoculars or telescopes have a very small area where the lenses line up and the full image can be seen which makes it hard to hold a phone up to them and get a full picture.
Need a way to finely adjust the position of the iPhone so it can assist with adjusting the camera into the optimal eye relief alignment with the binocular eyepiece.
My dad requested it be easy to adjust meaning simple inputs and not a lot of "messing with it".

Solution

Fine-Adjusting iPhone Holder

This device I designed for the iPhone 11 Pro (or equivalent external dimension phone) can adjust the position of the phone in 2 axes.

The device has 1 input per axis via a gripped wheel with an embedded nut. This nut will thread a bolt connected to the sled, which translates the whole sled. Each bolt had a thread pitch of 1mm which allows for very fine translation.

I designed all these parts in SolidWorks and printed them using my Ender 3 V2 in PLA.

This is a close up of the embedded nut in the gripped wheel. It was made by hot inserting the nut into the wheel.

Results

Worked as intended and was able to take pictures through the binoculars, also worked with some telescopes too.
Learned a lot about 3D printing and its mechanics as this was my first project with my personal 3D printer

The CAD files for the device are available on GrabCAD
