Printed in ABS over two years ago. Unsure of the settings. Design allows for some scaling for a press-fit on microscope eyepiece tubes.
Use rubber-bands or similar to hold the smartphone's camera in the correct position.
It's simple. Really just wanted a way to hold the phone at a right angle to the eyepiece within the exit pupil.
Improvements to this design would include:
-Collet and collet-nut for eyepiece (rather than press-fit)
-Integral clamping mechanism for phone
-Charging cable management
-Internal baffle to reduce reflections in bright environments
