At the end of last year I saw a Thor Mjolnir Rattle popup by IJustLikeMakingThings. Having just had a baby boy I knew I wanted to make one of these on my 3D printer. To design this I used Solidworks and built it full scale using reference material from the internet. I plan on printing a full scale version of this later but as a fun test print I built one scale down to be a baby rattle. The .STL files I included will be at full scale. I scaled them down to 30% for the baby rattle.

Step 1: Printing

The printer I used is a Creality CR-10 and I used Cura to slice each part.

I used the following settings for each part:

Layer Height: 0.1mm
Infill: 25%
Extruder Temp: 200 degrees celsius
Build Plate Temp: 65 degrees celsius
Flow: 100%
Build Plate Adhesion: Brim (I used a raft for the handle to give it a more stable base)
Supports: Triangles

Removing supports is fairly straight forward. Use cation removing the supports from the handle because they surround most of the handle.

Step 2: Assembly

Before glue any of the parts together, be sure to do a dry fit. You might need to shave off of little bit a the portion that fits into the body of the hammer. Use a x-acto knife or a file to knock down those small edges. If need be, use a file to open up the hole in the body. Take care not to remove to much on the handle or the hole for the handle. That needs to be nice and tight.

I used a Locite epoxy plastic bonder. This was my first time using it and it bonded everything real nice. Use small amounts evenly applied to the contacting surfaces.

The first glue up will be the cap and two hammer heads to the body. Painters tape does great holding it together.

Let that glue set up, my epoxy takes 20 minutes. Before gluing the handle on, pour in a tablespoon of rice through the hole for the handle. You could use anything one want for the rattle noise.

Finally glue on the handle and secure it with tape making sure that it sits square to the hammer.

Step 3: Finished-Final Thoughts

At this point I was done and my son loves it. I wanted to give it a nice paint job to give it that authentic Mjolnir look but I figured my son would be putting this in his mouth and I didn't want paint coming off.

Like I said I plan to make a full scale version of this design and I will painting that one.

Thank you for your interest in my little project for my son and thanks to IJustLikeMakingThings for giving me the inspiration.
