Growing up I always had a Lite Brite that entertained me for hours on end. This toy was originally release in 1967 and has seen a few revisions since it's first release however the retro tube-tv style from when I was a kid is the only version I think of when the name Lite Brite comes to mind.

This design consists of a box which holds a c7 light socket and bulb (led recommended for less heat), a panel with over 3,300 holes, and pegs which can be done in any colour. In my testing I could not find any filaments that light up like the Lite Brite pegs, so I opted to use Glow-in-the-Dark filament and black to take advantage of negative space and high-contrast. Perhaps someone knows of a filament that disperses light like the original toy does..? For this reason I have included a file named “PEG_hollow” which can be printed with a 0.1mm layer height for the thinnest possible walls and no top so that as much light can pass through as possible..

Would love to see everyone's creations!
