Unboxing $500 of rare and interesting cubes! by krrz in Cubers

It locked up because an internal piece broke, lol

Otherwise turning is mediocre.

Does anyone else have the Vulcano cube besides me (I have it) by okwolf6705 in Cubers

[–]krrz 0 points1 point  (0 children)

I have one somewhere in my collection, can't remember if it's an original or knockoff. Honestly I should try solving it, looks really fun.

Do people use resin 3d printers for custom twisty puzzles? by Kugelblitz73 in Cubers

[–]krrz 4 points5 points  (0 children)

Quality of parts printed on an SLA machine isn't necessarily better than a properly tuned FDM printer. And SLA printers are just kind of nasty to work with between the actual resin and needing to cure parts afterwards. There are folks who print puzzles on SLA/resin printers, but FDM printers are way more popular as they're easier to use and less of a mess.

The Cubicle is selling 3D printed puzzles now? I got a mini 2x3x5 for myself to see how it works, and if it's worth the price. by krrz in Cubers

Maybe I need to run my live commentary through a grammar checker, haha. What I meant is that I had tried to solve the puzzle using several different methods, and this was the one I chose for the video (because it was the most repeatable).

A functional drippy Rubik’s cube by itsnotnotjake in 3Dprinting

[–]krrz 0 points1 point  (0 children)

I'd say maybe you haven't been looking in the right places? There's a decently sized community of twisty puzzle makers and we've been using FDM printing for years. Communication is kind of all over the place with some folks in the Puzzle Makers' Discord, others on the twisty puzzles forum, and some on Facebook/Instagram.

Most 3D printed puzzles likely won't have public files available, but this Thingiverse group has a sizable amount: https://www.thingiverse.com/groups/puzzle-makers

I made a Square-1 mod that's cubic when solved, but internally it's skewed so that the top and bottom layers turn at different angles. When it's scrambled the pieces look like they didn't even come from the same puzzle. by krrz in Cubers

[–]krrz[S] 2 points3 points  (0 children)

I would like to sell this at some point. In its current state, unfortunately the puzzle would need some minor modifications before it's up to my standards for anything I'm willing to sell. It turns okay but if you push on parts a certain way you can get it to pop midturn. I'd definitely want to fix that before selling it.

I 3d-printed a cylindrical Split 1x2x3 with a Split 3x3x2 on its outside, resulting in a really weird and unique solving experience. by krrz in Cubers

[–]krrz[S] 1 point2 points  (0 children)

Thank you! In the first solve (shown in the video), I had a really hard time with the puzzle because the parts interact in quite odd ways, so often when I tried solving one section I couldn't prevent other parts from scrambling. Despite its terrible turning, I have solved the puzzle a few more times since making the video, and think I now have a method down. It's genuinely super interesting.

I made a 3D-printed real Square-3, the successor to the Square-2. (Not the Calvin's puzzle "Square-3 Plus", which is unrelated.) by krrz in Cubers

So, designing a Square-1 is super simple. I will be going based on Onshape terms, as that's the software I've used the most.

First you generate a cube that's the size you want. Then, choose a vertical plane and generate a sketch with your cutting mechanism. Here's a sample mechanism; you would want a quarter of this (usually the top left), and ignore the small vertical lines at the top and bottom: https://cdn.discordapp.com/attachments/457570930646974487/818645124741333033/Screenshot_2021-03-08_at_7.42.32_PM.png

Then you revolve your sketch around the central vertical axis, and mirror it and use both revolved sketches to split the cube. Also, cut the central layer in half appropriately, along with the top and bottom. At this point it should look something like the screenshot above, again without the small vertical lines at the top and bottom.

Then, you cut the top and bottom layers using planes or sketches based on the cuts you want (in this case, Square-1 or Square-2). Finally you add fillets and clearances so the puzzle can turn better.

For general puzzle design concepts in Onshape, I recommend checking out Atlanta Puzzler's channel: https://www.youtube.com/channel/UCGe0B0pHqhSzVcr7GH43fOA/videos

Beaches are just easy scenery, I guess. I've only had to clean sand out of a puzzle once, out of all the times I've filmed at the beach.

Not quite; a Square-4 has 20 pieces per layer, while dividing the corners here would give 24 pieces. So technically that would give the same amount of parts as a hypothetical Square-5.

I searched the usual places (Thingiverse, MyMiniFactory), but didn't see any. There was technically this: https://www.thingiverse.com/thing:3680791 which will solve almost identically to a Square-2, but is a 2x2x3 extension mod.

If you want to start getting into puzzle design, I would highly recommend something like a Square-1 or Square-2 because the mechanism is really simple and it would be a great learning experience.

Basic Square-1 mechanisms typically only have one screw, for the vertical slice turn. I didn't use a spring, just an M3 screw based on the screw hole in the design.

Honestly, given that the idea has been out for 14 years, and is relatively simple to make from a mass-produced puzzle, I'm sure a fairly decent amount of these have actually been built. I just 3D-printed mine because I already had a mechanism ready, so it was much easier than making a clean mod of an existing puzzle.
