I wanted to make a ring holder out of Mjolnir, so I did. I remixed ironQ's hammer. The handle wasn't long enough, so i extended it. I then remixed these rocks https://www.thingiverse.com/thing:4807562 and cut out an area that will fit the hammer head just right. I also remixed this Hammer: https://www.thingiverse.com/thing:1182831 . For some reason thingiverse won't let me add it to the design file.

You can print 3 pieces and assemble it, as I did. I left a hole in the head and the handle and attached them with a toothpick and some super glue. Or you can print the hammer as 1 piece, though I can't guarantee the handle won't break off over time.

Originally it was very light weight, so I drilled out the hammer head and the rock and filled it with fine hobby sand. I roughly finished the holes with a 3d pen, but because the hammer is glued into the rock, you'll never see where I drilled holes. I printed the handle at 100% infill, but the rest at 20% infill.

The height of the ring holder is 90.5mm, the length is 86.5mm, and the width is 56.5mm.

I used Dupli-Color metal cast metallic base coat for the the silver parts (I just had it lying around). The handle and the rocks were painted with Krylon Ultra-Flat Camouflage brown. I then went over the rocks with Rustoleum multicolor textured desert bisque to give it some more depth.
