The impossible dovetail puzzle (yet, another one)
I wanted to challenge my nephews and nieces for Christmas. While searching the Internet, I stumbled on Clickspring machined impossible dovetail puzzle on Youtube. It is an amazing job and I decided to design one myself. Taking it as an inspiration, I modified it a little and added some extras to make it more challenging. You can get it from MyMiniFactory.
You'll need a few things:
- One 10mm steel ball (second one optional). Option 1, Option 2
- Two 4mm x 2mm (diam x height) round neodymium magnets
- Optional: Pliers to insert the magnet
All parts print without supports and are exported with the right orientation to import directly to your favourite slicer. I used standard 0.2mm layer settings on my ZYYX+ 3D printer.
IMPORTANT: in order to work correctly, it has to be a tight fit. So, you'll need a well tuned printer. It prints perfect in my ZYYX+ but bear in mind that you may have to adjust some settings depending on your printer.
SPOILER ALERT! I don't want to publish here the secret to open it, if you want to know how it works, visit this link.
