About this 3D model

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'll need a few things: (Check BOM list) One 10mm steel ball (second one optional). Two 4mm x 2mm (diam x height) round neodymium magnets Glue 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 Prusa printers or 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. I asure you it's very funny watching friends and family go nuts trying to figure out how to open it ;)
