These 3d printed bits and bobs
fit together to make
a partly universal fitting to add a phone (camera) to the microscope.
It was to replace the one which came with the microscope
Whilst being very adaptable as far a suiting a vast range of cameras I was never happy with the idea of suction cups as a method of holding it in place. I did once have my iPod slide off.
Unfortunately the replacement design I had downloaded and printed out was
a) fragile - I snapped one bit trying to fit it together.
b) it didn't suit the iPhone 6s with its corner positioned camera.
probably fine with phones with a camera nearer half way across their body.
I had a look round on the Thingiverse site and found another design which looked a better bet.
Here are the parts once printed out
I had already fitted together the three parts which make up the bit at the top of the photo.
On the V shaped section there is a ball and socket joint in which the end of the screw fits. This is three sections around the ball. One of those snapped as it was too close a fit but everything still holds in place.
All the parts assembled
Fitted to the microscope
With camera firmly held in place
Fortunately my phone has an added cover over the back and sides which protects the volume and power buttons or the clamp would press and activate them. I think I will add some of the old style adhesive foam strip we used to use for sealing gaps in wooden window frames years ago. That should cushion any possible pressure on the phone's buttons.

I did have problems with keeping the items stuck on the printer bed to start with. I think it was the overall low temperature in the unheated conservatory. Things were cooling down too fast. Increased the bed temperature from the usual 60C to 63C and the extruding temperature from the usual 200C to 205C and all worked perfectly.

I toned down the sound. The printer has four cooling fans and four stepper motors which can be noisyish at times.
My grateful thanks to user 'falconphysics' for publishing the design on Thingiverse.
