Here's a DIY post I found with a really reasonable alternative. It's not in English but you'll be able to understand the process. It is well documented with images.

I'm on the list for the extender wish it had a shutter but it is what it is. Currently I put a lanyard off a thumb drive on my canon cover to prevent loss I can loop it around a camera strap if desired or in my case my strap has clips that attach to the short peices that are attached to the camera.

Glad you received it.

As for the solid version, I will look into it but I don't see much of a request.

Canon straps have an attached rubber eye-piece cover on them. You attach it to the eyepiece like so:

Just out of curiousity I decided to test how resistant to light the camera is without the eyepiece shutter. I set the camera on ISO 3200, used the body cap to close off the lens opening of the body, then used a bright LED flashlight to shine straight into the the eyepiece from about 10" away. Then I shot at assorted shutter speeds in 1EV increments. With an LED flashlight that reads on an incident light meter (ISO 100) 1/100 f/2.8 +0.5EV, the camera exhibits visible light leakage (looking at the back LCD of the camera) at 1/2 sec. exposure. I didn't take the additional effort to read images into Lightroom to see if detectable levels of image >0 (R-G-B) could be seen at higher shutter speeds, though. Your model of camera might be better or worse than what I tested.
I had not done similar testing in the film era...waste of film and processing costs! Before the semi silvered reflex mirrors, the mirror itself served as a better light trap to the film/sensor.
