Saturnus Puzzle Solution and 3D Print Files

For anybody that follows me, you have probably noticed that I've been on a puzzle kick the last few years. I usually build them from wood but this puzzle was part of a prize pack from Instructables for a puzzle contest I entered a while back.

I did solve this on my own but it took longer than I'd like to admit. After finishing, I took a look at the solution sheet and realized it wouldn't have helped much since it lacked most of the steps.

Hopefully, these instructions will help you if you get stuck solving your own puzzle. While I was at it, I pulled the dimensions and modeled it up in CAD. I added a few features to make it look nicer but mostly they were included to reduce print material. I've included the STL files for 3D Printing and STEP files for those that would like to modify the design - see last two steps. ** I will give an Instructables premium membership for the first person that 3D prints my design and post a picture of it in the comments.**

If you can't follow the pictures, this video shows the wood version being solved.

Step 1: Parts - Wood

There are six pieces of which five are unique.

Step 2: Parts - CAD

Note that I show CAD views along with the pictures for each step. The letter references (A-E) shown here are called out at the steps. On a side note, besides the two large cutouts, these parts should match the wood design.

Step 3: Solution - Steps 1 & 2

Add Part E to Part A. Note the location of the notch on Part E.

Step 4: Solution - Step 3

Add Part C to the assembly. Note that the slot on Part C goes over the narrow section of Part A.

Step 5: Solution - Step 4

There are two D Parts. Add one as shown. Note that "L" shaped slot after finishing this step. If you don't have it, back out and figure out what you did wrong.
