I teach at the secondary level, grades 9-12. We are going to make custom parts for robotics competitions that are after-school or part of the class.

Spent the summer using some Crickets in a Maker Space. Good prep for the FlashForge Dreamer we just setup.

With free Autodesk access for staff and students, we have started there. ABS seems better for durability and the heated build platform gives us flexibility to use APS or PLA. Not impressed with PLA and it's fragility and brittleness.

The 28 hour party might be better in parts ... especially depending on dependability of your printers. People learn better over time ... get to know their peers.

As another new task for us just starting ... but the students are at the same level ... or you have some good starters ... as they do, I will learn as they go. Younger are often impulsive and don't analyze what happens and don't get as far as fast ... and they need time to process. 28-Hour marathon?
