Raspberry Pi camera cases for telescopes

These files are for a simple case for the Raspberry Pi Camera that can be used to mount the camera on the telescope eyepiece. There are two files. One is for a one inch eyepiece and the second is for 1 1/4 inch eyepiece.
How to use them is described in a book "Science and Engineering Projects
Using the Arduino and Raspberry Pi " by Paul and David Bradt.
This book will be released in the summer of 2020.
