These are two designs to be used as protective shields attached to Streak Retinoscope & Indirect Ophthlamoscope. While face shields are already being mass produced for healthcare professionals, the challenge when it comes to ophthalmologists are different. These professionals have to use retinoscopes and ophthlamoscopes for diagnosis during the usage of which leaves them vulnerable. To tackle that I have created these simple designs.

The result is two sturdy, easy fit designs that can be produced with minimal material consumption and printed on budget 3D printers with quick print times.

Furthermore, to decrease the hassle of constantly printing and removing, this design can easily be stacked with the guide on how to create a stackable model given below.

Download the "Design Files.zip" folder under "other files" and extract to get stl files for both retinoscope & ophthalmoscope shields.

Material: Tested with PLA & PETG

To create a stackable model using the guide below, you have to get Autodesk Fusion 360. You can get Fusion360 license free for a year for personal use from this link

To create a stacked version of the shields:

Download the stl file for the shields from this page.
Open Fusion 360 and create a new design.
Click the "Insert" down arrow (under "Solid" menu) and select "Insert Mesh".
Select the shield stl file you downloaded to insert.
On the Browser right click on the top node of the tree (should be named "Unsaved") and click on "Do not capture Design History".
A warning will pop up but click "continue".
No right click on the model and select "Mesh to BRep".
Once that is done right click on Body1 from the tree in the Browser and select "Move Copy".
On the menu that pops up select "Create Copy".
On the "Z Distance" type "5.3 mm" and click "OK" [The shield is 5mm thick and we add 0.3mm (has to be equal to layer height) [5+0.3=5.3mm] to allow stacks].
Now you can click on Body2 repeat the above steps to create another copy.
You can finally go ahead and create as many copies as you want.
Once done right click on the top node of the tree under "Browser" and select "Save as STL" to save the version.
Remember that stacking needs a bit of a trial and error with your printer so see what number of stacks is suitable for your printer and play around with the settings on your slicer.
