Introduction: Custom Dice

My husband plays a lot of tabletop games, so I decided to make him some custom dice for his birthday and a personalized set for some friends who were getting married. While I was at it, I tried some cool alternate materials in some dice for myself. Sprinkles make great dice!

Step 1: Materials

You'll need some sort of silicone mold making material. There are tons of different kinds. I opted for a two part pink product.

casting resin

die

spoon or other utensil for stirring

toothpick or other disposable stick for stirring

disposable cups

stuff to put in your dice

Step 2: Mold

Mix up a small batch of silicone mold by the directions on the package. Whatever utensil you use to stir this material will be easily cleaned, so it doesn't need to be disposable.

Pour a small amount (1/4") of silicone in a disposable cup. I used disposable medicine cups and paper baking cups. If you have more than necessary for one mold, I recommend pouring a small amount in several cups so you can make several different molds.

Mix a fresh batch of silicone.

Pour a small amount of fresh mold maker over the dry silicone.

Place the die you want to mold in the center of the cup with the 1 side face up. Insert it at an angel so air doesn't get caught in the number depressions. Press it down so it makes contact with the dry silicone.

Fill the cup around the die with silicone, but stop at the top edge of the die.

Set aside to dry.

Step 3: Remove Die

When your silicone is dry, remove the dice from your mold(s).

Step 4: Resin

Mix up a batch of resin according to the package instructions with a disposable cup and stir stick.

Mix in your chosen items. I particularly liked the sprinkles and glitter. In these pictures, I used some small beads.

Pour the resin into your mold. Be careful to pour just enough that the resin is rounded on top and not concave. Don't put too much so that it spills out over the top of the mold either. You can dip your stir stick in the resin and add one drip at a time to the top if necessary. The resin will shrink a bit while it dries.

Step 5: Remove Dice

Pop your new dice out of your molds. The top will have no number depression, but you'll know that side is the 1.

If they dry and the top has shrunk and become concave, you can mix up another batch of resin and add a couple drops to the top.

Step 6: Personalize

To personalize the wedding dice, I drew the bride and groom's initials with a paint marker on a piece of clear plastic.

After pouring most of the resin into the mold, let the bubbles rise to the surface for a 10-30 min. When they rise to the top they'll pop.

Once you're happy with the lack of bubbles, carefully place the personalized plastic piece into the resin one side at a time like you would apply a screen protector. This will prevent new air bubbles from getting trapped underneath.

Gently pour the rest of the resin into the mold until you've got that nice concave top as described in past steps.

You may need to babysit the resin for a few hours. The center of the plastic kept wanting to bow up because it was thin, and as you can see in the image before it was placed, it was bowed up there too. When it would bow up, I would just use a toothpick to gently poke it back down. As the resin cures, it thickens and stops moving. Next time I'll use a thicker and flatter piece of plastic.

Step 7: Enjoy

Use a permanent marker to color in the number depressions. Add a single dot to the flat sides of your dice. No, they are not perfect and surely would't be allowed in a vegas Craps game, but they're fun, easy, and pretty.

These dice could be further customized with an Epilog laser cutter by adding designs, patterns, and monograms, though that's not the only thing I can make. Check out my portfolio if you don't believe me.

Cassandrie made it! (author)2016-08-03

So excited I found your tutorial and decided to make these myself! I've only had all the materials I need to make these for two days now, and I've already made two sets of dice! One clear set to test, and one with sprinkles in it, just like you did. I didn't try making my own silicone molds, instead I ordered those online, because I was afraid I would mess them up somehow. I may end up making my own though, because I love making my own dice so much! Thank you SO MUCH for the easy guide on how to make these! Even as a novice crafter, I'm not having any problems at all!

They look great! I'm go glad my ible was helpful and you're having fun with it. Keep on making!

Can I ask how you got such a uniform fill with the objects? My first cast resulted in a clear layer forming between where the sprinkles settled to the bottom and where the resin filled to the top.

author
Brooklyntonia (author)KittieBat 2016-03-17

It's been a while, but I think I continued to add sprinkles as I filled to pile more on as they settled.

Thank you :).

the only problem with this is, they arent usable. dice have to be precision balanced or they will not throw randomly, they will have a statisticly observable propensity to come up a certain way.

author
richieb28 (author)fixfireleo2016-01-01

In a perfect world, all dice would be perfectly balanced. Sadly, most dice are not. If you want perfectly balanced dice you buy them from the professional casino dice makers. You want personalized dice, you don't worry about balance.

Her dice are usable. She clearly states that they won't be useable at a vegas crap table. She knows that they are not perfect. Though one cannot take their own dice to a casino. That's called cheating. Nothing says that they cant be used for in home gaming. So it is a matter of personalization and fun rather than going for perfection.

Aside from that, the only dice that are precision balanced are casino dice. Otherwise they are just slammed in and out of industrial molds. At most they are weighed to ensure quality control. No non-casino dice maker is going balance check every die before shipping and packaging. It would add to the cost of the product. Most manufacturers just want to get the product out as cheap as possible

The numbers or pips (dots) throw the balance off. Also, the polishing process further changes the balance of typical dice. Even normal wear will throw the balance off of any die.

When it comes down to it, unless there is money on the line, very few dice are ever balance checked.

It's about fun, not perfection.

I think this would be an opportunity to deliberately craft some "gag" dice by placing something like lead shot in the mold which would cause one face to come up more than any other.

author
Brooklyntonia (author)fixfireleo2015-10-13

Yes, I did express that in the conclusion. But, they're pretty!

author
tenthz (author)Brooklyntonia2015-10-14

They would be great to use in various dice jewelry & other projects without having to canibalize your existing (possibly precision weighted) dice.

author
Brooklyntonia (author)tenthz2015-10-14

Very good point! They'd make great pendants.

author

Most all dice on the market are not exactly balanced. Unless purchasing specific dice that are designed to be balanced all dice favor a result.

Did you not read the whole article?

LuciferJr (author)2015-11-05

you could get a nicer finish on the dice if you put some acrylic pain in them then wipe the top. that's the way I do my dice I don't like the numbers on.

They look awesome!!

This is awesome! wish these supplies were easily and cheaply available here. I've been to craft stores and not found them...only online and that is way to expensive for me. :-(

What is the highest number of sides that you have done with this? Did you rip the mold ever during removal, or was it pretty forgiving?

author

The highest was the D12 you can see in the images. I thought it might be trouble since the sides are much smaller than the width of a D12, but no, it didn't rip or feel as though it might.

you can also use this method of mold making to do candy molds and make dice shaped candy for the gamers in you friends and family and the nice thing is you can get everything at Hobby Lobby

Brooklyntonia (author)randi_s2015-10-15

Good idea! Just make sure you use a food-safe mold maker.

author
Poppyburner (author)2015-10-13

Could one essentially make the mould from a putty of cheap silicone sealant and talcum powder?

Does that particular clear epoxy resin, yellow over time?

author

I have no idea if you could use silicone and talcum. It shouldn't yellow. I made them a few months back and there isn't any noticeable yellowing.

author

Thank you; though some say that it can take a few years for ultraviolet light (e.g. sunlight) to tint clear epoxy resins.

They'd be random enough for me. We always had our favoured dice when I was a kid. I had a d20 that seemed to have a slightly higher chance of rolling a natural 20 or 1. Of course, all my friends thought I was wrong but I swear, this one time... :)

Great instructable.

Procrastinateher (author)2015-10-13

I wonder, would it be possible to press something into the top edge to get the number depression on that final side?

Though I guess since the depressions don't need to be transparent, you could always carefully use a tool to remove that tiny bit of resin (like this guy finishing off his sprinkle cake stand https://www.youtube.com/watch?v=vGmnBYGD8D0)

author
kuro41 (author)Procrastinateher2015-10-13

Why not just make a two part mold? You can get a perfect copy that way.

author

I tried using a flap of modeling material on the top of the die for the 1 depression but the resin kept seeping out of the edges around it and made it a mess. You could do a two part mold, but I wanted to keep it simple.

author
CharlieA11 (author)2015-10-13

Can't wait to make one!

author
VirginiaNutu (author)2015-10-13

is it correctly balanced or does it favor a side?

author

As stated in the conclusion, they will not be perfectly random.

author
ku5e (author)2015-10-13

Just a question. Would it not be better to place the die on the one side in a solid/flat bottom container then, the cover with resin (to 1/4 inch above the die), then remove from the container? This would assure a flat one side and is easier than pouring molding material twice. just my $.02

author
Brooklyntonia (author)ku5e2015-10-13

That would likely work, but you risk the die moving around and getting a lot of molding material under it. If you used sticky tack to hold it down, I'd give it a shot that way. I just always had a bit of molding material left after molding something. Putting the remainder into a cup to use later as a base was practical.

kinnikunky (author)2015-10-12

Beautiful! I was planning to cast some as well but hadn't imagined they'd come out so nice! I plan to make 2 part moulds so as to get the top as well. One idea I had, that might prove to be too difficult, is to suspend tiny objects in the centre (like a little skull, or flower..). Your candies turned out well it looks. Did they end up touching / breach
the sides a lot?

author
Brooklyntonia (author)kinnikunky2015-10-12

No, none of the candy breached the sides. To suspend, fill part of the mold with resin, wait for it to dry, then add your center item, and finish filling. Keep in mind that a centered item will most likely make your die even less random.

Good luck, and come back to post pics when you're done! I'd love to see what you make.

That doesn't surprise me since I assume you're talking about the one made of candy sprinkles.
