Pinecil, but an electric toothbrush.

@PINE64@fosstodon.org how can this happen?

As far as I can tell process.stdout is unbuffered in #NodeJS. Bypassing with a writeStream to fd 1 is giving a substantial improvement in tests.

Praying to the #3DPrinting gods that these parameters will work.

It's just a cube.
