The final 3d print of the macro flash diffuser has now been completed.
Printed in PETG plastic. This has a little flexability so is not as brittle as PLA.
First time printing PETG. This was not an easy task and caused quite a bit of frustration. Cleaning up of the parts took quite a while and caused one or two swear words on the way ( I may have even invented a few new swear words when I managed to cut myself during the cleaning process). ;-)
Added a hood to bounce a little more light in front of the lens. All that is left to do now is to paint the outside faces black. The diffuser lens is printed with clear PLA and is removable so I have the oppertunity to change the level of diffusion if required. The three parts are a friction fit so no glue required. Taken a couple of test shots with this and the results are not looking too bad.
The real test will come when I can find a shiny insect to photograph.
Finally, the diffuser weighs in at 400g but feels quite good on the camera.
