This thing is an adapter for mounting your phone to a microscope. Using user parameters, you can change dimensions.

Overview, background and requirements
This is a helpful device for allowing students to take pictures on their phones of microscopes. I, as a student, was/am very frustrated with the immensely difficult process of lining up my mobile just right, to get a good picture to show to my parents and document the moment. Microscopes are occasionally used at my school, so I really wanted to be able to look back on it. I could spend 5-10 minutes just getting ONE photo, which I now realise was a massive waste of time.
With this device, however, students can easily capture the slide in under 30 seconds. Simply distribute around the classroom, or put them on a front desk; students can take one, slide it on to the eyepiece, pop their phone in and "wham". It can also be used, by simply opening the camera app, as a way to get multiple students viewing the same microscope.
Unfortunately, there is some prep required. You need to measure the outer diameter of the microscope, and figure out the tolerances of the printer. Add them together and you put this in the user parameters. I would recommend, as you cannot measure each student's phone, you make 5x one size, add 10mm in both directions, make 5 of those, add 10mm again …… This way, there will always be some that will fit the phone.
I know that not all students have camera phones. But this is no issue - this item is an OPTIONAL EXTRA, not a comulsory standard. Students without mobiles can always look over to another microscope, for reasons described above.
Please see my guide, below, on each of the parameters as you may need to adjust other ones.
Happy printing and I hope your lessons go well!
Lesson Plan and Activity
This is really meant to be a supplementary device to your lesson. But, as Thingiverse is nagging me, I'll give you some suggestions.
In Biology, when studying plant and animal cells under the microscope, it can be used to magnify even further the small parts of the cell - to further student's learning. When we did a leaf disection, and put the pattern under the microscope, I found this gadget very useful as it allowed me to 1) show people, 2) print out and it now hangs on my wall (it was a very beautiful and intricate pattern) and 3) magnify the small folds to see cells in greater detail.
The sky really is the limit with this device. It is a great enabler for lessons, and can really turn a lesson viewed by students as "boring" (I never thought that!!!) into a fantastic fun-filled study. Because who doesn't love using their mobiles in the lesson!
All you need is a 3d printer and filament. Depending on how many you would like to make, the filament needed will change; but you can always print them one at a time. In fact, I would recommend printing a test one to fit on the microscope - you may have to adjust the parameters more. For measuring, you can use a ruler (or if you have callipers they are even more accurate). When slicing, take care to design supports efficiently.
How to change
Please load the .f3d file (Fusion Archive) into Fusion 360. Then, under the "Modify" tab, select "Change Parameters".
The group "User Parameters" should be opened automatically, but if it isn't please click the drop down arrow.
From here, move your mouse over to the parameter you want to change. There is an explanation of what ALL of them do in the segment below. Hover over the "Expression" Column of your chosen paramter, and click the number. You can now type whatever number you want, and hit enter. (Please note that you do not write "mm" after the number - to adjust the units, click on the previous column)
As soon as you make the change, the model should be updated. Click "Close" at the bottom of the Parameters Dialogue to close it. Repeat this process until you have changed everything you want.
