I had a business trip to Anchorage Alaska so I got inspired to 3D print the ESB electrobinoculars. I was initially daunted by the leather strap, but I bought a half inch strap from Amazon Amazon.com and a snap kit from Michaels and it was pretty easy. I used a stiff brush to lightly weather the edges. I'm really happy with how this turned out and I honestly want to wear it every time I go out in the snow. This is the model I printed https://www.thingiverse.com/thing:2762113
Looks great!
I finished mine just a couple of weeks ago. It had been laying around for years but never finished it. I got the print from April Storm on Etsy.
