Pentakis Dodecahedral 60-sided die

Pentakis Dodecahedral 60-sided die 3d printed Games Dice
This is a 60-sided die (d60) based on a polyhedron known as a Pentakis Dodecahedron (the shape you get when you put a 5-sided pyramid on top of each of the faces of a dodecahedron, or d12). It should have a face come up with a random number on it every time you roll it. I''m not sure until I get mine, but it might have the up-face slightly offset from where the bottom face is, that is, it won't be directly above the bottom face but the top face will be flat. This is a fairly large die, which should help with legibility, but you still need to ink this with a pen or something similar.
cm: 3.462 w x 3.462 d x 3.464 h
in: 1.363 w x 1.363 d x 1.364 h

I for one appreciate that it's fully solid, since it means there's no chance of getting a big bubble in the support material - it's guaranteed to roll well, especially if the material is detailed enough that asymmetric roughness isn't a big issue :) Also, it will have some serious heft if I order it in a heavy material. (Serious cost, too, but it's still nice to have the option available.)

Picofarad (24 Aug 2010 04:54): Some designers on here have done similar designs with a less dense center filled with support material. The die is slightly bigger in diameter than this, bur cost is about 2/3 in strong flexible white and about 1/2 in detail materials.

I wonder if there is a way we can drop the cost ofc this one .. the full color sandstone is very nice .. but as you said .. it is hard to read .. the plain white of this model ... was more than the full color sandstone :(

YES! It finally works in full color! http://www.shapeways.com/model/143503/red__green__and_blue_d60.html has the die in all its splendor (although I am biased, of course). This one is unintentionally smaller than the other, but only by 3 mm in diameter. The dice numbers should be a bit more deeply imprinted, too. Right now that one is only available in full color sandstone so I can get feedback on the color quality on different buyers' prints. I am concerned about the size of the numbers and the detail level of the grainy material, so I will try to upload some more colors soon. YAY!

( note- using it like a d6 means counting 1-9 and 60 as 6)

I did order a metal one. It's still in production. Of course I'll post some photos when it arrives, as well as the inked transparent one. Have you seen the pictures on the forum here of the terra-cotta colored super -detailed material and green super-detailed wax? It looks amazing, but it's not available through Shapeways as of yet. This will make all sorts of new things possible if it's available. I can't wait. I'll post the rest of my collection on cosmicdices.blogspot.com soon. I also have a wishlist of shapes I want done, but some of them are very tricky. I'll put that on my blog as well. I don't know autoCAD or anything like that, but I have a lot of ideas, and am reasonably good at Google Sketchup. It would be nice if there was a way to have a collaborative account on here so that people with different skills could team up and realize ideas together. I wish Lou Zocchi would have a Shapeways store. That guy's like the demigod of dice. Someone should also take on the challenge of making more of Kevin Cook's paper dice designs at dicecollector.com into dice. Oh, and if you want an excuse to use the d60, just use it as a d6 and only read the first digit.

Maybe i'm wrong about the sandstone. I was assuming that it was less detailed than transparent detail, but the specs for materials on here list them as being equivalent, So it might work. Also I have no idea why every comment I make appears twice. Sorry about that.

Picofarad! You are amazing! I am amazed by your photos of this thing, and I really, REALLY appreciate your feedback. Do you think that if the numbers get colored and imprinted in a textured model, then this could work in Full Color Sandstone? If I simply start making it larger while keeping it solid, that will shoot the price way, way up... I could go for maybe about 4.2 cm in diameter, but pushing it up to 5 cm would just launch the price up higher and higher -- when you ink it at this size, could you post some more photos from eye level to table level? My gaming group has a few illegible dice (Yellow text on a green-and-red-swirled d20? What were they thinking?) and they slow down play a lot, not to mention how awful they look. I don't imagine I will be playing a game that needs d60s any time soon, but I do want the numbers to be easily recognizable, of course. Did you order a metal one? If so, I hope you won't be rolling it on any easily-damaged surfaces... Or glass tables... Good luck, and I wish you many natural 60s!

Didn't seem like I can upload photos on here so: http://cosmicdices.blogspot.com/2010/08/d60.html

I just received this in the mail today. It's pretty cool. It rolls very fairly and it's easy to determine which side is up. The shape is totally 100% viable as a usable die. The only issues are dealing with material/level of detail. I ordered it in transparent detail. Some of the faces are much more easily read than others. The 36 and 5 are the best, as they're at the 'top' and 'bottom' of the printing process. Oriented this way, you can see striations that go horizontally upward from the 3D printing process. so the 'top' and 'bottom' are very nice and crisp and bright and the sides have a rougher texture. You have to kind of squint and look close to read the numbers on some of the sides, but they're all legible. If you hold it up to the light and look through the translucent material, the numbers are all very readable. I'll upload some macro shots soon. If I were to make suggestions, I would say make it a bit bigger, maybe 2 1/4 - 2 1/2 inches in diameter or 5 or 6 cm in diameter. And make the numbers deeper, They're very shallow. I'd say at minimum 2 times deeper. That would allow someone to sand down the sides with 600 grit sandpaper and not risk sanding the numbers off completely, and make inking it easier. As it is, you would have to meticulously draw in the ink, because if you tried to quickly ink a number and wipe away excess, the texture would trap a lot of ink and just create an ugly mess. It's a very satisfying size now, and I suggest making it bigger reluctantly, but I would increase the size a bit. And personally, I'd say that I'd much rather have a solid transparent detail copy than a hollow metal one, but I'll reserve that judgment until my metal one arrives in the mail. I imagine Kevin's suggesting a hollow metal one because the detail might be slightly greater in steel, and a hollow one would cost a lot less, but we'll see. Making both available would probably be best. If Shapeways develops their high detail option further, I would definitely want to see what this looks like in that material. When I have time, I'm going to try to patiently ink this with a .01mm drafting pen and see what it looks like. Inked it would be completely legible and easily usable in a game. For someone as into exotic dice shapes as me, worth the effort, but maybe not for the casual gamer. I would strongly suggest NOT making it in colored sandstone or anything less detailed than the most detailed options offered here, because even that is pushing it. Hope all that helps.

Thanks Picofarad! There's another author who just announced he was trying to texture a slightly different d60 (rhombic instead of pentakis, so quadrilateral faces), but he hasn't yet released it, so your feedback on these colorless dice will let me know whether or not I should continue trying to texture this die.
August 5, 2010, 6:54 am
I'm having some of these printed. I understand the risks of being the guinea pig, but i'm too curious not to. I'll let everyone know I'll let everyone know how it turns out. P.S. Hello Kevin. I just did a trade with you not too long ago.

Kevin: I still haven't ordered mine; I have been trying and trying to make a texture for the die that colors the numbers black and the rest of the die in a pattern, but this hasn't proved fruitful. Rolling this die, made in steel, would seriously damage most tabletops, and I don't know how to round the corners either. Picofarad: I am not very good at 3D modeling yet; the polyhedron was generated by Mathematica and the numbers were just extruded text, rotated into position, and boolean-subtracted from the polyhedron. This was difficult and time-consuming for me, and because I don't understand texturing I can't make this much better. So, unless the custom order is very simple, probably not. If anyone wants to texture this model or make it a co-creator thing, I have started a thread on the forums at http://www.shapeways.com/forum/index.php?t=msg&th=3078&start=0&S=c8b2f52e57f3889cee977525540e7a0c with the component parts for this model as an attachment (text separate from polyhedron, but it won't take much to subtract the text from the die shape). I don't care about seeing a profit from selling these things, but I do want to hold one in my hand, and I hope other people share my sentiment.

Do you take custom orders?
August 2, 2010, 5:45 pm
Any news on the viability of this model as a die?
July 28, 2010, 2:05 pm
If the model works (ie has a flat side facing up) ... Please consider making a hollow version to reduce the cost ... $220 US ... is a bit much for a steel d60 :)
