Base for RPG miniatures projecting a FOV

This cylindrical base for RPG minis has a built-in field of view (FOV) cone that can be adjusted to different angles. The FOV is projected onto the table, making it easy to see what the mini can see.

I find the FOV features of tabletop simulators like Roll20 useful, so I wanted to create something similar for real-life use.

It’s made of three printable parts and a light source. Here are the STL files:

• Base
• Slider
• Top

I used these balloon lights as light sources. You can use something else as long as it fits into the rails of the bottom part (w: 10 mm, h: 10 mm, d: 40 mm) leaving some space in the depth direction to allow the adjustable beam angle to function properly. You might need some adhesive to glue the light to the slider. Sticky Tack, poster putty, or Patafix should do the trick.
