Doug Engel is a prolific puzzle designer. He has an etsy shop where he sells his designs made out of 3D printers. Note that he made one metal puzzle and this should be a limited edition, so grab one while you can :)
The easiest in the series. It's looking great and display well. Not super difficult. A nice warm-up. Don't forget that usually disassembling a puzzle is easier than reassembling it. So keep track of what you do.... :)
No need to explain the name I guess :)
The goal is to seperate the pieces. A nice fidget toy as well as a puzzle. Not super difficult but rewarding. In my opinion, this would make a nice level 1 or 2 hanayama puzzle. Hope the designer thought about asking Hanayama to produce it !
Now more challenging: Six Circles
Finally: the Borromean Cage
Tricky as there are many moving parts. The goal is to free the 4 star constellation inside.
Note that the solution is displayed for this puzzle on the product page, so don't be tempted to look at it !
Many of these puzzles were presented at past IPP. Even if they did not get a prize, they are preatty unique in their respective type and for the soft price tag, I can only recommend to have a go !
Very suitable for beginners as well as for seasoned puzzlers.
If the links on my post don't work well, you can search on etsy: Puzzleatomik
And normally you should find easily the shop.... plenty of puzzles to buy !!!
