Smartphone Solar Eclipse Filter (Parametric)

This holder is a completely parametric model to adapt a pair of paper solar eclipse viewing glasses to work as a solar filter for a smartphone camera.  This should work with any smartphone, with or without a camera bump, and with or without a case (instructions and parameter setting provided below).  

STL provided is for an iPhone13 Pro with a Torras case for reference. Feel free to DM me or drop in the comments your parameters that work and phone model, and I will update them in the chart below along with your phone model. 

Note:  DO NOT  look or point your phone's camera directly at the sun without the proper solar protection in the form of solar viewing glasses or specialized solar filters.  Follow all instructions on your glasses or filter.  Also ensure the glasses / filter meet the proper certifications.  Note a similar setup worked for me last year for photographing the annular eclipse, but YMMV and be mindful of your phone's thermal sensors.

Parameters:

Note: Round measurements up to the nearest 0.5mm

Note:  Parameters are designed to center the lens to the camera bump, you may need to adjust the positioning accordingly if the lens is too small for your camera's bump

Instructions

1. Set up parameters, slice and send to printer.  Note, some supports may be required depending on your camera opening width and bridging capability.

2. Test fit phone, test to ensure that adapter doesn't block camera's view
   
   
    
3. Cut solar glasses as shown 
   Note: it doesn't matter if you use the right or left lens as long as its the same one you took the measurements from and the lens and frame cover the entire opening in the adapter.
   
   
    
4. Insert the lens in the slot, ensure it seats all the way in and there's no light bleed
   Important: ensure the glasses are facing the correct outward orientation
   
   
    
5. Slide assembly over your phone
   
   
    
6. Go outside and test 
    
7. Happy eclipse photographing
