BACK IN STOCK: 3D Print Canon Eyecup Eg Eyepiece Extender for 7D 5D 1D Cameras

Canon Eyecup Eyepiece Extender 7D 5D 1D

One of the most popular/visited reviews on our site is the JJC EC-6 Eyepiece Eg Extender. If you're not familiar with the eyepiece extender, it extends the eyecup 5/8" (15mm) from the camera body. This is useful for eyeglass wearers and others to keep the tip of the nose from touching the camera screen. Canon does make their own EP-EX15 and EP-EX15 II eyepiece extender but they don't fit any of the more recent EOS cameras.

We have been getting emails on where the aftermarket eyepiece extender can be purchased from. Unfortunately, they are discontinued and no longer being made even though the Canon eyecup (Eg) is still being used on current and new Canon cameras.

To help other photographers out who are searching for this extender, we created a CAD file (from scratch) of the eyepiece extender which will allow us to print a 3D model of it. The 3D printed version is almost an exact duplicate of JJC version but with some slight improved modifications:
  • Aftermarket : The 3rd party extender came with its own eyecup with a flat back which is slightly different from the Eg eyecup that comes with your camera.
  • 3D Printed : Grooves were cut out so that the OEM (Eg) eyecup that came with the camera can be used without have to buy new ones. If you lost or need replacements, you can purchase from Amazon, B&H Photo and Adorama.
  • Aftermarket : The 3rd party extender came with a cheap plastic lens to "help" magnify your view.
  • 3D Printed : Sole purpose of this is to extend the eyecup so that your face is not near or touching the screen. Also, the plastic lens only made your view even more distorted.
One thing that will still be the same is that some of the corners may be cut off when looking through the viewfinder because your view is now further away. Also, the viewfinder and OEM eyecup is rectangular while the extenders opening is a square. So this will require you to make slight adjustments to the positioning of your head when looking through the viewfinder.


The eyepiece extender fits the following Canon EOS cameras that uses Eg eyecups:
If you're looking for an extender and your camera is not listed above, take a look at our DIY: Nikon/Canon DSLR Camera DK-17M Magnifiying Eyecup/Eyepiece Mod for a list of other Canon compatible extenders.


*NOTE* 3D prints and fitment will vary depending on the machine, nozzle, filament and/or settings. 3D eyecup extenders may have a snug fit when mounting onto camera and reinstalling rubber eyecup. Below are images of what the 3D printed item looks like
