To start with, I'm a shower shaver. I just like that my face is already warm and moist, and that I don't have to worry about the mess. Up until about 15 years ago, Goody made a smaller compact travel mirror that was perfect for use when shower shaving. However, out of the blue they stopped making it, and since then I've been working with a mirror broken in several places (glass and housing) that is held together by multiple iterations of Superglue and Epoxy. I've scoured the earth trying to find something comparable to replace my last broken mirror and have failed . . . until now!
This model is the perfect sized travel shaving mirror. It is designed to utilize a 3" circle glass mirror (here are the ones I purchased for referece: https://www.amazon.com/gp/product/B07KZQM4VP/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1)
I used ABS to withstand a hot shower, and printed at 100% infill for strength and a heavier weight.
Update 2/2/19 | FYI traveled for the first time since I made this. Used it for two shaves, and it performed perfectly - good grip & handled the hot water.

Print each part seperately. Insert mirror into body (optionally glue with a thin layer of your favorite water-proof adhesive), then insert rim with tabs down into the body until each tab clips into its corresponding slot (slots/tabs are all identical and positioned at top/bottom/left/right inside of body).
