Hey forum,

This is my latest puzzle, the royal pentultimate. It has 6 axis of rotation, with 4 cuts per axis, resulting in 24 cuts total.









Although the photos look quite ugly, the puzzle look much nicer In real life. I had to apply a lot of superglue to keep the stickers on, and for some reason, it really shows in the photos. I will be making a v2 with flat faces, and hopefully I will be able to iron the stickers on.

Video

As you can tell form the video, the turning quality of this puzzle is far less than perfect, but I plan on do a second version with an improved mechanism. I hate to draw comparisons, but the challenge of getting this puzzle to turn well is on the same level as Oskar's Brilliant 17x17x17. When executing a slice turn on his 17x17x17, there are 64 parts that need to be rotated; on the royal pentultimate, there are 60. To make matters worse, the direction of the force used to turn the slice layer in the royal pentultimate is not normal(meaning perpendicular) to the cut planes to any of the parts being rotated, meaning that some of the force is transferred into a different direction, causing alignment and "squishyness" issues; due to the cubic nature of the 17x17x17, this problem is non existent.

I will not be selling copies of this puzzle, as it does not function well enough. With all of the things I have learned from building this puzzle, I think I can get v2 to work much better, and assuming that works well, I will auction a copy off.

Oh my God!!! You sir, are a legend. What I'm upset about is that there is not a chance that will ever win the auction. Ever.

Slightly off topic, but is the Master Pentultimate on the right your design? I plan on buying a Master Pentultimate from you in the near future, and I would much prefer a flat design rather than pillowed.

WOW. That is amazing. With all of these "royal" puzzles lately you surely are the "king" :lol:

Again, I feel your pain for the stickering. Wow. Some of those stickers are the size of a flea!

Great work. It looks like it turns pretty well in the video.

Great work Eric. It looks like to me the turning is very good if the puzzle is all aligned, otherwise it locks up a bit.

This is fantastic and the turning far surpasses my expectations, however alignment seems to be extremely important :D Excellent job.

First of all this puzzle is amazing. Second, would it be rude to ask how many pieces are in it?

Without a doubt, i think any of the guys that hang out in the gelatinbrain thread would be able to tackle this one pretty easily.

The part count is 544, not including the core.

Oh I'll gladly have a go at this magnificent piece of pure awesomeness!

Is there any particular reason for skipping the professor version?

Yes, it's very hard to get the internal bandaging for the professor version working.

Wow! That is awesome!

You mentioned that you thought the turning quality was bad, and that it didn't function well, but by the video, it looks fine. Also, do you know how to solve it?

I will be praying that this is uploaded to Shapeways one day... the pictures are amazing, but when I watched the video, my jaw hit the floor. Superb puzzle, great job as always, I hope to own some of your puzzles one day!

Ummm... I think you skipped a cube (or two).

Awesome puzzle, though!
