Is there a smaller triangular moodlite?

[Syco54645]

So I am looking at messing with this project but was curious if there is a smaller triangle moodlite available. When looking originally I found https://www.thingiverse.com/thing:3354082, which the size is perfect for what I am after.

There is this post but i am unsure of the state of the files for this. https://moodlite.co.uk/index.php?topic=45.0
