Canon SLR DSLR adjustable Eyepiece - update

thingiverse

I had a problem: I'm nearsighted. There are correcting eyepieces on the market, but they don't fit to my eyes because I have too many diopters and an astigmatism. There are two solutions: Taking pictures with glasses or build glasses for my camera: et voilà ! :-) The eye piece consists of three parts. Just glue them together. You can choose the right center part which fits to your thickness of your glasses. Take an old eyeglass lens and cut it out (24 mm x 16 mm) and you have a perfectly adjusted camera. And for those who want to wear glasses: I also added a protection Ring. This is printed with varioshore TPU with an infill of 25%, layerhight of 0,15mm and full foaming temperature (means 220 °C nozzle temperature). I can tell you: It's really soft :-D. I added a saw template to cut out a standard glass blank. It's a little oversized so that you can sand it into a press fit. I put a piece of foam rubber in it to protect the plastic lens during sawing.
