Thanks for the inspiration...again!3D print version. As with the earlier puzzle, it's less manual skill to make, smaller, and so, easier to carry in a pocket! You've done it again. Great instructable.
Great work and appreciated inspiration. As always puzzles are fun to try. A 3D printed version popped into my head right off. This joins my puzzle drawer cache!
Well written instructions and a very nice project.You may want to edit the final email address. It looks like "shrimware" should be shrimpware. Love your logo!
