Life Size Thor's Hammer (Mjolnir)

pinshape

Welcome all who are worthy! I promise this is the only worthy joke you'll hear here. There's more in the video, though. This is a fully 3D printed Mjolnir, and I made it life-size. I'm sure it's not the exact dimensions of the movie prop but it's close, and it can be scaled pretty easily. This version of Thor's Hammer is specifically from The Dark World movie. If you want to see it in action, watch this video: https://youtu.be/D6DdESIhi4c. I provided two different options for the main part of the hammer. It prints in 2 sections, and they are identical, so just print 2 of them. There is a hollow one if you're looking to save some filament (this is the option I took), but I also provided a solid one that will print in a better orientation if you're able to spare the extra filament. The solid option will also provide more weight, which could add to the realism of it. Print Settings: * Rafts: No * Support: Minimal * Resolution: 0.3mm * Infill: 20% All of these settings are flexible, but you'll need some supports for the little slot on the bottom of the bigger portion of it. I didn't use any supports while printing, and I just had to do some clean up. I printed at 0.3mm layer height, but you could increase that for better details. I was trying to save some filament, and infill doesn't matter too much here. Post-Processing: Step 1: Print all the parts. Step 2: Sand the parts down as much as possible. The details on the handle and the outside of the hammer can be pretty hard to get smooth, but do your best. Start with a coarse grit sandpaper in the ballpark of 100 grit, then move up to 400 or above to get the best results. Step 3: Glue the parts together. Use the printed pins to hold the parts in place, then apply glue to those pins to adhere them together. I used a Gorilla Glue Two Part Epoxy, glued the parts and held them for a bit until they dried. Then once the parts are together, take a paint brush or something similar to apply the epoxy generously over any cracks or seams you want to cover. Step 4: Prime the hammer. We chose to use a black spray primer from Krylon. Coat the hammer at least twice, letting it dry completely in between coats. Just lightly spray across the surface using a normal spray painting technique. Don't stress too much about the detailed areas at this point. Step 5: Painting the hammer. We used a Hammered Metal spray paint. Specifically silver colored. Apply 3 coats of this, letting it dry completely in between. If needed, you can sand any rough areas in between coats. Just use your judgement on what looks best. The paint should fully cover the hammer. Step 6: Paint the handle. For this, you'll need a paint brush and some brown acrylic paint. Paint the brown on the lower areas of the handle, leaving the silver rings and base of the handle as is. Make use of multiple brushes to get into hard-to-reach areas. Apply 3 coats of this to get a smooth but plentiful coverage of paint. Step 7: Apply a wash. We took some silver and black acrylic paint, mixed it, and watered it down significantly then applied it to the details on the handle and on the sides of the hammer. Use a paper towel or spare paint brush to dab off excess. This will give the recessed areas a more defined shadow. Step 8: Rough it up. Take sandpaper to the paint on the bulk of the hammer to give it a worn and used look. Go around the edges and just lightly sand it to give it a more textured look. Then take some paper towels you used to clean off the wash and lightly dust that darker color across the body for even more texture. Step 9: Apply a finish coat. You can get some spray clear coat and just spray the whole thing once it's completely dry and done. This will help protect it from damage like scratches to the paint.
