Introduction: Making a Stained-Glass D20

Today I'm going to take you through the steps needed to make your very own stained-glass d20.  There are some special tools and materials required so I'm going to call them out here:

Tools you will need:
A laser cutter / etcher
Vector editor software (i.e. Inkscape)
A cutting board with an angle measurement
A glass scorer
Score running pliers for glass (optional, but recommended)
A soldering iron
A small brush for the flux
An icosahedron jig

Materials you will need:
A sheet of stained glass (12" x 12")
A scrap piece of cardboard (roughly 11" x 11")
Adhesive backed copper foil
Solder
Flux
Soap

Once you have gathered everything that you need move on to the first step.  If you don't have a laser cutter the last step includes options for adding the numbers in other ways.  Also, since a lot of people have been asking in the comments, these, along with other art, can be purchased from B&B Glassworks (http://www.bandbglassworks.com)

Step 1: Making the Cardboard Template

The first thing we're going to do is create a template to hold the glass pieces still while we're etching them.  To do this we need to open up our vector editing software and create an equilateral triangle; that is a triangle that has the same length on all three sides. Some software and laser cutters interact differently but you have to make sure that the outline of this triangle will be a cut line as opposed to an etched line.  Once you have done that you can duplicate that triangle 19 times and organize them in a compact area while making sure to leave some space between them.  Once you have them all laid out draw a square around them using a cut line so that the finished jig will fit nicely against the edge of the laser cutter's bed.

The next step is to put numbers in each triangle.  Here you can use any font that you like but remember that the top of the numbers always face a point of the triangle.  Also, if you're going to etch on the back of the glass, like we did, you need to remember to mirror your numbers so they show up correctly on the front.

Now send this to your laser cutter and let it go on your sheet of cardboard.  If it etches the numbers in the cardboard that's ok, we're not going to use those pieces for anything anyway.  What we want are the holes that are left behind.

Step 2: Preparing the Stained-Glass Triangles

Now we need to cut 20 triangles out of our sheet of stained glass that match the template that we created.  The easiest way to do that is to cut a stip of glass the same height as the triangles we cut in the jig.  In the example pictures we used a strip that was 1.5" wide because our triangles ended up being 1.5" tall. Place the strip flush across the bottom of your cutting board and set your angle guide to 60 degrees.  Follow your angle guide with your scorer so you end up with a 60 degree angle cut off the end of your glass strip.  Depending on the kind of glass you bought you might simply need to flip it over to get the other side of the triangle, but the glass in the demo pictures is textured on the back, so we can only cut on the front, so we need to change our cutting guide to 60 degrees the other way.  However you end up doing it, make sure that you are making your cuts and angle adjustments as precisely as you can, because if the triangles are not correctly shaped they will not make a good-looking d20.

Once you have 20 good pieces we can etch the numbers on them.  Place each triangle in one of the holes of the cardboard template on the laser cutter's cutting surface.  Now you can use the same file that we used to make the template but be sure to set your laser to etch only!  We don't want to cut around the holes again!

Step 3: Putting It All Together

Now that we have perfectly shaped triangles with numbers on them it's time to put it all together into a d20!  The first step is to wrap the edges of each triangle in the copper foil tape.  This gives us something for the solder to adhere to.

At this point you may want to consult a d20 or get some really good pictures from the internet, because the location of the numbers is very important.

Choose the first five triangles you will be using and place them face-down in the jig making sure that they are evenly aligned and that the flat tops of them form a continuous flat plane.  I’ve found it best to brush some flux in the bottom of the little bowl that the triangles make before aligning them, then melt some solder so it drips on the spot where all five points come together.  That will hold them firmly in place while you solder the other seams.  Once you have all the seams soldered on the inside for the first five pieces, rotate the glass in the jig and add additional triangles and solder them in place on the inside.

Solder all the triangles together except for the last five pieces.  These pieces will make a “lid”, so once you are done you should have a 15 triangle bowl and a five triangle lid, both of which are soldered only on the inside.  Now, flip them over and solder the seams on the outside keeping the bowl and the lid separate.  Once you have all the outside seams soldered you can clean the pieces with soap and warm water to get the flux off the inside.  The last step is to place the lid on the bowl and solder it in place, then clean it again with soap and warm water and you are done!  Congratulations!

!! Important !!
While soldering the pieces together be sure that you are putting the correct numbers next to each other!

Step 4: What If You Don't Have a Laser Cutter?

If you don't have access to a laser cutter / etcher, don't let that dissuade you!  There are other options for getting the numbers on the glass.

Chemical Etching
Chemical Etching is a common technique used to etch glass.  The result is usually more of a frosted look than what you would get with the laser cutter but it is still a nice look.  There are several Instructables that will show you how to do this and get very nice results.  I would recommend etching the pieces using the chemical process at the same point as you would use the laser cutter because it will be much easier to do while they are still flat.

Sand Blasting
Sand blasting would work in much the same way as the chemical etching process.  You would mask off the areas that you want to remain intact and they would be protected from the sand.  Sand blasting can be adjusted to get the look that you want.  It can be anything from a light frost to even deeper results than the laster cutter.

Vinyl Stickers
Your local craft store contains a wide assortment of vinyl stickers that you can use to add numbers to your d20.  The adhesive will be affected by the heat from the soldering iron and the flux so I would recommend that you completely finish and clean the d20 before sticking the numbers on.

Really neat project. Great life counter for Magic the Gathering.
Wonder how it can illuminated (from the inside) -- leds, maybe?
How would batteries be replaced?

You don't have to use a laser-cut template, though, do you. If you're handy with a pencil and protractor, you could cut the templates by hand, and you could use aerosol glass-frosting to add the numbers.

Big question, though: can you actually roll them?

author

Don't roll it, hang it from your rear-view mirror.

CaseyBorders (author)Kiteman2012-02-14

You could do it all by hand but in my experience it's a LOT harder and you don't get consistant results.

You can roll them as long as it's on carpet or another soft surface!

As I liked to tell my customers, feel free to roll them. They'll work at least one time before destroying your table or cracking (depending on the surface). Though it's surprising how tough they are. But something like this is not really meant to be a functional gaming tool. :)

Since the protruding, metal vertices should already be taking most of the impact of rolling, if you were to get some of the paint-on rubberised coating commonly used on tool handles, one or two layers would probably reduce the flex of the vertices to the point where it wouldn't crack the glass, especially if it was rolled gently. (Throwing it on the table is probably not going to be a good idea regardless.)

Of course, you're going to have to be very precise with your construction if you want the die to roll fairly.

not everyone has access to a laser cutter/etcher, although it would be meticulous and tedious, hand cut stencils aren't that difficult but there are other options as well. Print the wanted symbols on clear acetate and hand cut with a sharp razor or if you have access to a cricut you could cut out individual symbols on triangle shaped "masks" and use a cream etcher. For a more rustic look you could just draw the symbols with a marker and use a dremel with a diamond dust bit to engrave over the marker.

I may be mistaken but I think what Kiteman was trying to say is that you can offer options for some steps that wouldn't scare the less tool endowed away from attempting a recreation

There are a couple of variations that could be used. You could use a glass etching chemical but, as I said, I've never had much luck with those. You could also get vinyl stickers from a hobby store and use those. I'll add a step to the end that will show some alternatives.

Dear. God....
I can't tell you how bad I want to make these, I mean I really really really want one of these. I play D&D and I love collecting dice. Sadly I have NONE of the tools necessary to make these, nor the money to buy said tools. These are stunning and I absolutely MUST find a way to get one in my house some how some way lol.

You dear, are a genius.

I was going to say that.

I would pay money for this.

Awesome! I haven't done stained glass in a long time, but I know mine never came out that well! Wonderful job :)

author

Thank you very much! My brother and mother run a stained-glass company. You can check out their work at http://www.bandbglassworks.com Be sure to have a look at the gallery!

author

I would love some of those pieces like the Assassins Creed one and the Bobba Fett and the ! How much do they run on average? How much would one of these D20's be? How much would it be to commission a Skyrim dragon logo one?

author

I'm glad you like it! You'd really need to email my brother and mother about pricing. Their address is BandBGlassworks@gmail.com. They do all kinds of custom work so they can work up anything that you want!

Oh, you use the copper foil to make numbers! Very clever! Do you mind if I add that to the list of options at the end of this instructable?

author
jifka (author)CaseyBorders2012-02-16

Sure - I also use a grinder and a hand-made jig to bevel each facet so they fit together snugly.

A very well thought out and prepared "ible" about a unique and pretty creation. However, like many who are involved in something or know something , it's assumed that others will know as well, I think these die are for some kind of game but have no idea which one. I think it would be helpful if you added a description of what they are and how they are used to the beginning of your "ible"

As a work of art I would imagine these would be spectacular sat on a base with led's shining through them

d20's are used in a variety of table-top RPGs like Dungeons and Dragons. These are intended to be an art piece that shows off nerd pride as opposed to actually being used in game.
