Here’s another recent project I did for DnD. There are various conditions that characters can get in the game. For example you might be hit by a spell and end up paralyzed. Or ‘Charmed’, which can basically mean you can attack anyone except the person who charmed you.

Tracking those conditions & remembering their effects each turn can be tricky. Especially if the DM is running a lot of things simultaneously.

Here’s my version. They’re lasercut acrylic rings, that can either be draped over a miniature or put around the base:
I polled my various DMs to get their opinions on which conditions which were most important, as well as required quantities of each ring. I did the design using Python and Jupyter notebooks. I wrote some code to make the shapes, write the text in a different colour, and put the variable diameter outline in place. To my mind that’s the killer feature, as the rings take up as little space as possible during both storage & play.

I came up with a good method of fairly quick mass production. First step was to lay some masking tape down on the lasercutter bed, and score the dimensions of the stock onto it. That way I could reliably line up the piece later.

Next, I engraved the text with the laser, and then rubbed ordinary acrylic paint into the pits left behind. This leaves a beautifully vivid colour inlay that is hard to get any other way.

The excess paint is wiped off, and the material is transferred back to the lasercutter for final cutting.

The entire set fits together neatly into a plastic storage tray.
