3D printing - AMScope / Canon adaptor, for Barlow telescope lens. (And many others)
Posted: Mon Apr 20, 2020 8:29 am
I made an adaptor because the 2x Barlow lens for attaching a camera to a telescope was £12, the equivalent for the microscope was £80 - though not the same company!
Version one took me ages, and followed the contours of the Barlow lens, and caused all sorts of problems to model and didn't fit too well.
That was when version 2 was realised - the diameter of the adaptor mount on the microscope matched the diameter of the Barlow 2x lens screwed into the camera!
It was a much simpler job then of designing a straight tube with a bit extra to screw to the microscope adaptor mount.
I've made a dust cap for it, and 3D printed washers to fine tune the focusing to directly match the eyepiece.
It prints slightly narrower than the Barlow lens so that it can be sanded down in the top 1/3 of the cylinder, to make a slightly rough and very good fitting.
I can put my camera on the adaptor by pushing gently and rotating a little side to side. It comes to rest without any form of wobble at all.
The adaptor that came with the microscope wobbles slightly due to being adjustable for many cameras.

It takes around 3.5 hours to print everything.
