I kept thinking I wanted to get a little more experience with mold making and casting. I have nieces, nephews, and friends who are all playing various tabletop roleplaying games (TTRPGs) like Dungeons & Dragons regularly. Dice would make great gifts for all of those people. I have also been enjoying the work of some of the resin artists I have found making dice. I didn’t really want to do a bunch of resin casting in my home studio, but had become aware of some less-toxic stone-based “eco resin” casting materials like Jesmonite.

Back in March, I started working on making a big 42mm 20-sided die (a D20, in TTRPG parlance). I modeled it in Blender with a font I like (and have properly licensed), and set about 3D printing one from which to make molds. Although I have been knocking out all sorts of perfect models on my resin printer, there were some issues with getting my Anycubic machine to produce a flawless D20. At first, it was mechanical. It took me a bit to realize the plate had worked itself loose in a way apparently isn’t expected, then a bit to get it fixed correctly. Minor issues after that were eventually resolved by choosing the right resin.

From that print and a printed mold form, I made silicone molds, eventually coming up with a slightly-modified cap mold style that seems to work pretty well.

I cast a bunch of dice in Jesmonite, playing with various mixing and pouring techniques, different pigments, and various approaches to keeping bubbles and voids from ruining the casts. I mostly settled on using an old dental vibration table, some tapping and stretching of the filled molds, and a pressure pot for the later.

I have been painting in the numbers with acrylic paint, and finishing by polishing with bees’ wax.

There are a lot more finished dice than I am showing in this post.  I haven’t managed to photograph all of them yet.  I may add more in the future.

Once I had some big dice, I decided I needed to make some cool gift boxes for them. That’s for another post, though.

I made a video walking through the journey of getting some finished Jemonite chonks:

I created the Spiral Crystal Light-Up Pop Up Card for the prompt “reverse” in Chibitronics’ project in 2024. The basic mechanical design of the card is based on a piece by Masahiro Chatani.  This uses an LED Circuit Sticker, conductive thread, conductive fabric tape, and custom-cut copper traces for the circuit.

The Enchanted Forest

A pop up card made from cutting and folding a single sheet of stock depicts a stag standing framed by the convergence of rows of trees receding into the distance. The branches overhead form whirls and spirals. The background is a green textured paper (momigami) with the white card backlit against it.

Godar Blot Skull Pins

Godar Blot skull pins – hardwood inlay skull pins from white oak, walnut and, padauk. The white oak is dominant on one pin and the walnut is dominant on the other.

I didn’t post the wood inlay Mastodon logo pins I made a couple years ago but, they came out so well that I periodically think of other things that would make good pin designs. In the spirit of the season and, since I rarely get around to the “spooky season” projects I envision these days, I made some skull pins inspired by my old Godar Blot design.

There are two variants: one where white oak is dominant, with walnut for the eyes and nose and, padauk for the spiral on the forehead and, another where walnut is dominant with white oak for the eye and nose and, padauk for the spiral.

I was making these for friends and family but, I ended up making a few extras. They are up in the shop, if you want one (light or dark).
