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.
If you can't follow the pictures, this video shows the wood version being solved.
There are six pieces of which five are unique.
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.
Add Part E to Part A. Note the location of the notch on Part E.
Add Part C to the assembly. Note that the slot on Part C goes over the narrow section of Part A.
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.
Slide the tab of Part B into the "L slot".
Here is the tricky part. You will need to rotate D1 by 90 degrees in order to insert the last piece.
Add the second D Part. Rotate D1 back.
If you buy or print the puzzle, you might want to print out this sheet for reference.
If you modify anything, please post your creation :).
This is a follow-up to my previous post after assembly. This printed and assembled very easily. Waiting to hear back.
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.
