Nikon APS-C DSLR Viewfinder cover & Selfie mirror

thingiverse

This is a remix of the Nikon APS-C viewfinder hard cover (https://www.thingiverse.com/thing:1587542). I wanted to create a hotshoe-mounted selfie mirror, since entry-level Nikon DSLRs do not have pivoting live view screens. This cover seemed like an excellent starting point, so I didn't need to model the hotshoe or hinge. However, it was too small to be useful with a mirror attached. I split the original cover STL into two pieces, the hinge and actual cover. Then, I enlarged the cover to allow for a larger mirror, and reattached it. The cover now serves as dual-purpose: - Flip down to cover the viewfinder, blocking unwanted light leaks during long shutter exposures. It will block a small portion of the live view screen though, so frame your shot before flipping it down. - Flip up to use as a selfie mirror. It's not perfect, but it's easy to carry and gets the job done. Tested with a Nikon D3500. It should work with other D3*00 cameras as well.
