Impossible Dovetail Magnet Puzzle Box

thingiverse

I've created my own version of a commonly known puzzle that I first saw in this video: https://youtu.be/xp-PENvptu0\r\n\r\nLooking for an experimental project to learn about 3D printing and clearances needed, I found that adding a buffer of around 0.15mm on each side between parts works well. These parts straight off the printer fit tightly but work perfectly after some working and cleaning.\r\n\r\nI've also seen examples of this puzzle on this site, and while it's not a remix, it's my own take with similarities to existing designs.\r\n\r\nExperimenting with spray painting the bottom half for contrast was a success, and I'll see how well it holds up. Another experiment that worked well was some inlaid text on the lid using nail polish.\r\n\r\nI used a 6x3 mm N52 Neodymium Disc: http://r.ebay.com/73SqQq\r\nIt's super glued into the recess printed for it in the lid, and the press fit was almost tight enough but then the ball would pull it out, so super glue was necessary to make it stay put.\r\n\r\nFor the ball I used an 11mm ball that my kids had from magnet construction toys.\r\n\r\nNo supports or rafts were needed for this model and I printed with 0.2mm layer height. It took about 10 hours to print both parts side by side.\r\n\r\nUPDATE: 05/03/2018 I added files for v2.1 with slightly more clearance so the 2 parts fit together pretty much straight off the printer (thanks to feedback from Qrome).
