    Brilliant! That's awesome. Thanks for the tip - it can get super confusing, especially when you are making a more detailed maze.

    Hi there, the easiest way would be to download the STL files from the instructable, and then search online for a 3D printing service. You will then be able to upload the STL files and get a quote for them to make one and send it to you. I have no idea what the cost would be, you can look at a service like https://www.3dhubs.com/3d-printing/ and the nice part about it is that you can select the material and colors you like. Hope that helps!

    Hallo Guido, de basis van het maken van de holle cilinder is: maak een tekening met zowel de binnen- als buitencirkel erop. Wanneer u vervolgens het gebied gaat extruderen, kunt u alleen het gedeelte tussen die twee cirkels selecteren en dat gedeelte extruderen. Het snijgereedschap bevindt zich in het menu Wijzigen en heet Trim (in het Engels). U kunt het ook selecteren door op "T" op het toetsenbord te drukken. Als de tool is geselecteerd, zal Fusion 360 elk stukje geometrie dat kan worden verwijderd uitlichten, en als je erop klikt, wordt het verwijderd. Hoop dat dat helpt!

    Thanks! I wish I could take credit for the approach but I had to dig around a bit to find it. Most other CAD systems have a Wrap command to do the same thing in a single step but where there's a will there's a way ;¬D) BTW that's a really cool looking material! Who makes it?

    Wow that finish looks awesome! Do you happen to have a link for that PLA pro? Always on the lookout for great printing PLA.

    Looks awesome!

    Hiya, thanks for the shout out! Nesting puzzles are definitely a lot of fun. The four parts at the top of the main image in the instructable are exactly that - the smaller one goes into the medium one, and then that assembly goes into the larger one which is finished with the top cover. The process to design the puzzles is basically the same as shown here, the main differences are that you would repeat Step 5, only placing the drawing on the inside surface of the unwrapped sphere. You would also need to consider the thickness of the cylinder as well as the depth and width of the path, to make sure that you don't end up with holes in the cylinder. So for example if you make the cylinder wall 5mm thick, you can have a maze path on either side with a depth of 2mm and still have a 1mm wall be…

You would also need to consider the thickness of the cylinder as well as the depth and width of the path, to make sure that you don't end up with holes in the cylinder. So for example if you make the cylinder wall 5mm thick, you can have a maze path on either side with a depth of 2mm and still have a 1mm wall between them where the paths cross. And a path of 2mm deep would mean that the width of the top surface of the path would be 3.8 mm wide (1.9 mm offset from the centre of the path) which would allow an angle of 44 degrees for the side walls of the path, giving you that V shaped groove (which is ideal for 3D printing).The second thing to keep in mind is that when the inner components are completed together, the base of the inner cylinder needs a slot aligned with the opening at the top of the outer cylinder in order for it to fit into the next cylinder, but again the steps in this instructable can be applied to make that happen. Definitely something I'd like to try in the future, and if/when I do I'll add some additional steps to show how it's done. Stay safe, hopefully you'll get access to that 3D printer soon.

    Aha! Thanks for clarifying Tom, I'll have to update the title. As for being meditative, it's varied widely for the people that I've given these too ;¬D)

    Hi Jace! Thanks for the kind comments! Hopefully these will answer your questions:1) In the main image for the instructable, I've printed the different designs using a silk metallic PLA, which makes them look like they are made of metal. In my experience, silk PLA filament varies widely in terms of it's shininess, and these PLAs from Eryone are some of the nicest ones that I've found. The copper one in particular: https://www.amazon.com/Filament-1-75mm-ERYONE-Prin... , and here is the link to the silver: https://www.amazon.com/Eryone-Printer-Filament-Dim... (I did notice that they have an even brighter silver available which I will have to try in the future: https://www.amazon.com/Filament-1-75mm-ERYONE-Prin... )Printing with these filaments is pretty much the same as printing with regula…

In the photo because it's so hi Rez you see all the imperfections, but in real life the matte finish actually helps hide any surface jankiness that makes it look really smooth.2) [Disclaimer: this is personal opinion only, I'm not any kind of expert :¬D) ] I use a CraftBot Plus printer (https://us.craftbot.com/collections/craftbot-plus-...) which was actually a Kickstarter project back in the day, so I did manage to get it for about USD $750 - although I had to wait for 2 years to get it :¬D). What I love about it is it's incredibly sturdy build, heated bed, decent build volume and screw driven Z-axis. An awesome machine, and if I had $1500 to spend, I would definitely look into the Plus Pro in the link above.However, if I was looking to get into it today, I would seriously look at the Creality Ender 5 (https://www.amazon.com/Official-Creality-Mainboard... I have a few Industrial Designer friends who have picked one up in the last year and are really happy with it. At the USD $500 price point, it seems like a very decent mix of price and features. What they said are the pros:• Sturdy frame• Decent build volume• Heated bed• Assisted bed levelling • Dual Z axis for stability• Reasonably quietThere's also a good online community of Ender users for troubleshooting and support, as well as lots of available upgrades to fine tune the printer. For all these reasons I think that it's a really good option for not a lot of cash.Again, don't take my word for it, there are a couple of excellent YouTube channels that feature detailed reviews of lots of 3D machines, my favourites are MakersMuse (https://www.youtube.com/playlist?list=PLTCCNNvHC8P... and Joel the 3D Printing Nerd (https://www.youtube.com/channel/UC_7aK9PpYTqt08ERh...There are lots of options out there, good luck and happy 3D printing!

    Absolutely! This particular sample pretty much followed the sizing and path size of the sample on Thingiverse but with a different pattern. Next versions are going to use narrower grooves which will allow you to fit much more of the maze on the cylinder and decide how hard to make it. The two approaches I was thinking of trying were 1) to make the paths generally longer so there's lots of doubling back to get to the next path which feels counterintuitive, and 2) making the false paths much deeper (more segments) to make it a little more challenging to get back to the junction where you can get back on the right path. The only thing to keep in mind is the offset for the paths, and making the extrusion of the path 50% of the width, so you can have the 45 degree angles in the wall. And obvio…

And obviously adjust the dimensions of the guide pin accordingly. If you do make a more challenging one, would love to see a photo posted!

    Created another inner core with the circular pattern shown in Step 13. Came out great, but surprisingly (to me) solving the puzzle didn't really feel that much different than the original maze, I guess because a circular motion is really a series of small horizontal and vertical motions together. But this does raise some interesting possibilities, like what would a series of overlapping concentric circles be like to solve? Can you have a completely freeform labyrinth pattern as well?

    Hi Lenny - it would be cool for sure, I think you'd have to use an SLA process to get a nice clear outer cap.

    Thanks so much!

    LOL - fiendish idea! It's totally possible, in fact the silver and copper cylinders you see in the background of the main image are similar to that. It's a Russian doll type situation with them all nesting inside each other which I found on Thingiverse: https://www.thingiverse.com/thing:2410748 But I like your idea of mazes on two surfaces, maybe one that is predominantly horizontal and the other predominantly vertically....

    That looks awesome!

    Quick tip for Step 6 - make sure to extend the groove path past to the top edge of the cylinder, and then when you select the paths to extrude, make sure to include that section that is above the cylinder. Then when you extrude it, you should automatically have the cut in the top edge of the cylinder, and that basically eliminates the need for Step 7 :¬D)

    VERY impressive design! I'm having a lot of fun printing and assembling the project. One tip I've learned is to take your time and print a smaller number of parts at once and assemble as you go. Initially I tried to fill the print bed with as many parts as possible but inevitably one thing would fail and that would cause all the other bits to fail as well. But I found that if I take my time and print a smaller number of parts that I need as I go, the parts printed better and the print times are shorter so that is more satisfying.Can't wait to get the final assembly together and post the results here. Thank you for such an awesome project!
